Aerographer's Mate

E-1 to E-3 (Junior Enlisted) · Navy

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

AG 'A' School runs at Keesler AFB (81st Training Wing) — joint with the Air Force 1W0X1 weather pipeline — and produces an AGAN who can take a surface weather observation and encode a correct METAR. That is the floor. The ceiling is the Navy METOC career: shipboard aerology, METOC detachment forecast support, air wing weather, or a path into the FNMOC product community. The first billet decides more than most AGANs realize — go in with a read on what track you want before the detailer calls.

The Honest MOS Read
You graduated AG 'A' School at Keesler AFB and checked into your first command with a qualification card, a basic METAR encoding handbook, and a set of assumptions about what Navy weather work looks like. Most of those assumptions were wrong in at least one important way, and the senior AG2 who met you at the quarterdeck knew it before you walked in the door. Welcome to the AG pipeline. The Aerographer's Mate rating serves three distinct worlds: the ship's aerology division on surface combatants and amphibious ships, the shore-based Naval Meteorology and Oceanography Command (NAVMETOCCOM) detachment or regional forecast center, and the air wing or air station weather support office. Each world runs a different tempo, a different watch bill, and a different relationship with the forecast product. What they share is this: the observation you take or the sounding you launch is the first link in a data chain that flows to fleet commanders, aviation operations officers, and ship captains making operational decisions. A bad link is not a paperwork problem. At the AGAN tier, your world is the observation schedule. Surface weather observations are your primary domain — sky condition encoding in oktas and cloud height, visibility, present weather phenomena, temperature and dew point to the tenth, altimeter setting, wind speed and direction at the standard 10-meter height, and the hour-coded METAR you transmit on the WMO schedule before the next observation window opens. The WMO Technical Regulations Volume I (WMO-No. 49) and the WMO Guide to Instruments and Methods of Observation (WMO-No. 8) are the international standards your METAR is encoded against. The duty AG2 does not care what you thought the ceiling height was — she cares what the sky actually shows and whether your encoding matches it. Upper-air soundings are the second major AGAN task in units that run a rawinsonde program. Balloon preparation is harder than it looks the first time — fill to the correct free lift for the ascent rate required, secure the radiosonde payload at the correct wire length, verify radiosonde initialization and signal acquisition before the launch window, launch cleanly, track acquisition on the ground station, and monitor mandatory and significant levels through the sounding. A missed mandatory level at 850 mb or 500 mb feeds a gap into the fleet weather database FNMOC uses to drive model guidance. Miss the sounding and the senior AG on watch will have the answer in the section log before you finish the paperwork. Shipboard aerology division duty has a particular operational intensity that the METOC detachment ashore does not fully replicate. Underway, you are in a 3- or 4-person division where every watch rotation is visible to the OIC and every weather product goes directly into the ship's operational picture. The Officer of the Deck may ask the duty AG what the sea state will be at 2000Z during the underway refueling window. That question is going to the AG2 or the AG1 — but the AGAN who cannot support the answer because the 1600Z sounding has a data gap or the morning surface observation was re-coded twice is the AGAN whose name is on the section log for the wrong reason. Garrison aerology at a METOC detachment is a different tempo — more observation-station discipline, more structured training schedule, more time for the NWAE study habit. But the standard for observation accuracy does not change with the pace of the day. The WMO synoptic report time is the WMO synoptic report time whether the duty forecaster is running a high-consequence aviation brief at 0700Z or the section has a light day. The NWAE for AG3 (E-4) is the first professional gate in the rating and it arrives faster than most AGANs expect. Pull the current Bibliography for Advancement (BIB) from MyNavyHR in the first month on station. The BIB is the test. Start with the AG Rate Training Manual (NAVEDTRA series) and work through the WMO observation references, the OPNAVINST 3140.1 aerology requirements, and the NWP 1-03.1 doctrine. The AGAN who walks into the AG3 NWAE cold is the AGAN who watches the advancement slate from the watch bill. The NEC and C-school question will come earlier than you expect as well. The AGW (aerographer/weather forecaster NEC) is the primary NEC identifier for the rating's operational forecasting billets. Oceanography-support NECs also exist within the NAVMETOCCOM enterprise. Pull NAVPERS 18068 to read the AG-rate NEC entries before you sit with the career counselor — know what the codes actually mean in terms of billet type, school length, and post-school assignment before you commit to a path from scuttlebutt.
Career Arc
  • 01AG 'A' School at Keesler AFB — joint pipeline with USAF 1W0X1, surface and upper-air observation foundations, METAR/SPECI encoding, rawinsonde basics, synoptic chart reading.
  • 02First assignment: METOC detachment, ship's aerology division, air wing weather office, or NAVMETOCCOM regional element — watch bill entry, observation certification, PQS line items.
  • 03Surface weather observation certification — METAR/SPECI encoding correct to WMO standard with zero systematic errors on duty AG2 spot-check.
  • 04Rawinsonde upper-air sounding certification — solo launch, track, and data QC on schedule.
  • 05Synoptic chart plotting and pattern identification competency signed off by senior AG.
  • 06NWAE BIB for AG3 opened, study log established on the LCPO's timeline.
  • 07AG3 advancement via Navy Enlisted Advancement System — NWAE exam, FMS-based cutoff per NAVADMIN cycle.
Common Screwups
  • ×OPSEC breach on METOC products. METOC support in a deployed or operationally active environment produces products that are sensitive — fleet routing, aviation route weather, significant weather warnings for underway operations. One social media post with a product visible, a unit designation in the background, or a geotag near the operational area opens an OPSEC investigation that ends the clearance and the enlistment together.
  • ×Missing a mandatory observation window without notifying the duty forecaster. A gap in the surface or upper-air observation record is a data-quality event that flows into the FNMOC model guidance chain. The section log captures it. The OIC reads the section log.
  • ×Falsifying or estimating an instrument reading rather than correcting the underlying discrepancy. A barometer you estimated instead of re-leveling is a systematic error in every surface observation for the duration. The next PMEL calibration audit traces it to your signature on the maintenance log.
  • ×Going around the duty AG2 to the flight operations officer or ship's OOD with a weather call you are not certified to deliver. The met chain runs through the senior AG on watch. The OIC hears about it before the next brief rotation.
  • ×NJP or DUI. In a small rating with a small community, the read propagates at the speed of fleet email. The clearance conversation and the NEC pipeline conversation end the same day.

A Day in the Life

  • 0500-0600Wake up in the barracks or on-base housing. Quick check of the weather station status if you are on watch — any sensor alarms overnight, any PMEL calibration flags the duty section left on the log. PT gear on, walk or drive to the section gym or the command PT formation.
  • 0600-0700Command PT or section PT to OPNAVINST 6110.1 standard. At a METOC detachment or ship's aerology division PT is typically three days per week with the section; the other two days are individual PT time to the command schedule. PRT cycle discipline is year-round — Good Low is the floor, Good Medium opens the advancement conversation.
  • 0700-0800Hygiene, chow, change into utilities or cover. Pre-watch turnover from the off-going duty section — observation log review, instrument status, any sensor discrepancies flagged, PMEL actions due today, the duty forecaster's briefing notes from the overnight watch.
  • 0800-0830Quarters at the METOC section or ship's aerology division. LCPO reads accountability, puts out the plan of the day. Watch bill for the day confirmed — observation schedule, sounding assignments, instrument maintenance blocks, model guidance pull assignments for the duty AG2's morning analysis.
  • 0830-1000Primary observation block. The 0900Z (or local-equivalent) surface synoptic observation — sky survey, visibility, present weather, instrument readings, METAR encode and transmission. Rawinsonde prep if the 1200Z sounding is assigned — balloon fill, radiosonde initialization, pre-launch signal check on the ground station software.
  • 1000-1100Rawinsonde sounding launch if assigned — launch, track acquisition, monitor mandatory and significant levels through the RAOB software, log the sounding. Post-launch documentation and QC check with the duty AG2. On non-sounding days: instrument maintenance block, publication updates, FNMOC/workstation product pulls for the morning brief package.
  • 1100-1130Support the duty AG2's morning synoptic analysis setup — chart plotting, model guidance printouts, satellite imagery retrieval. Watch the AG2 work through the analysis. Ask the question after the brief, not during.
  • 1130-1230Chow. Eat with the other AGANs and AG3s — not with the LPO, who eats with the chiefs (or with the AG2 if the section is small). Quick instrument status check and PMEL log review before the afternoon block.
  • 1230-1500Afternoon block — varies daily. PQS sign-off sessions with the AG2 or AG3 on line items you have been working. NWAE study block if the watch bill allows. Afternoon observation (1500Z SYNOP where required). Instrument calibration checks. Section publications review — OPNAVINST 3140.1 sections relevant to your billet, WMO-No. 49 present-weather table review, BIB chapter for the current study block.
  • 1500-1600NWAE study block (when the watch bill allows). The LCPO who sees you with the BIB open during slow time approves more study time on the next watch rotation. This is not optional work — the AG3 NWAE cycle arrives faster than AGANs believe and the FMS is built across the whole cycle, not the month before the exam.
  • 1600-1630End-of-watch turnover. Observation log closed for the shift, instrument status documented, PMEL action log updated, sounding record filed. Duty section on-coming AG has everything she needs for the overnight watch before you hand off the keys.
  • 1630-1800Released. Most days. Field deployments with a METOC detachment, underway periods on a ship's aerology division, air wing support surges, and standing duty change this hour by hours or days. PRT prep, study, personal time.
  • 1800-2100Personal time. Single AGAN in the barracks — gym, study, BIB chapter work at the desk. The NWAE study habit lives in this block more than anywhere else in the week — 30 minutes at the desk with the rate manual and a notepad is how the advancement slate happens.
  • 2100-2200Instrument status check if you are on an overnight rotation. Pre-sounding prep if the 0000Z sounding is assigned. Tomorrow's uniform and watch-bill assignments confirmed. The duty AG2 who calls at 2130 with a weather question expects a coherent answer, not 'I will check the manual in the morning.'
  • 2200Lights out. Tomorrow starts at 0500.
  • Underway / deployed (ship's aerology division or METOC detachment in the field)The schedule compresses to the watch rotation. Observations run on the synoptic schedule regardless of sea state or operational tempo. Rawinsonde soundings launch from the fantail or the designated launch station in 25-knot wind and 10-foot swells when the schedule requires it. The OIC brief is the forcing function — whatever the duty AG needs from the AGAN section to brief the captain is what happens before 0700. The AGAN who learns to operate in the deployed rhythm during the first underway period is the AGAN the AG2 trusts on the second one.

Weekly Cadence

The Mon-Fri rhythm at the AGAN tier runs on the LCPO's plan of the week and the WMO observation schedule, not on your own calendar. Monday sets the week's training plan — the LCPO confirms PQS sign-off sessions with the AG2 or AG3 who are qualified to sign, the instrument maintenance schedule for the week, the sounding assignments, the study-time allocation if the section has NWAE candidates in cycle, and any inspection or readiness milestone the OIC is tracking. The AGAN's job on Monday is to know the week's plan before noon and to have the instruments and publications current before the Tuesday morning observation block. Tuesday through Thursday are the operational core. The observation schedule runs every day at the synoptic times — nothing moves the 0000Z, 0600Z, 1200Z, 1800Z surface observation window. Rawinsonde soundings fall on the command's assigned schedule, typically one or two per day where the unit runs an upper-air program. Instrument maintenance falls in the off-watch blocks. Section training — synoptic analysis drill with the duty AG2, model guidance interpretation with the AG1, OPNAVINST 3140.1 sections, WMO observation standard review — falls in the afternoon blocks the LCPO has blocked for it. The AGAN who brings a question from the previous day's observation to the morning section training earns more training time; the AGAN who sits quietly and never engages earns less. Friday is plan-of-the-week-out for the next week. The LCPO publishes the watch bill, the section sync confirms the next week's training and inspection calendar, and the AG1 or AG2 walks the instrument log for the weekly readiness brief. The AGAN who has a clean observation log, a current instrument maintenance record, and a documented NWAE study block for the week walks out of Friday with the LCPO's weekly read on her side. Field rotations and underway periods collapse the Mon-Fri rhythm entirely — when the detachment is deployed or the ship is underway, the observation schedule is the calendar and everything else fits in the margins.

Key Skills — How to Drill Each

  1. 01
    Take a complete surface weather observation — sky condition, visibility, present weather, temperature/dew point, altimeter setting, wind — and encode a correct METAR/SPECI before the duty AG2 has to issue a correction.
    Work through the observation systematically every time in the same sequence: sky condition from the horizon at each cardinal azimuth (not just overhead), visibility to the standard measurement point, present weather phenomena coded against the WMO present-weather table in WMO-No. 49, temperature and dew point from the calibrated thermometer screen, altimeter from the calibrated mercury or digital barometer, wind from the anemometer at the standard 10-meter height. The sequence discipline is what prevents the systematic omissions — the AGAN who takes each element in a different order every shift is the AGAN who misses the scattered layer because she went straight to the temperature. Have the duty AG2 review your first twenty observations against the WMO standard before you transmit independently; ask her to find the error on the three you got wrong before the correction lands.
  2. 02
    Launch, track, and terminate a rawinsonde upper-air sounding — balloon prep, radiosonde attach, RAOB software, mandatory-level and significant-level extraction — on the observation-schedule timeline.
    Rawinsonde prep is a procedure, not a judgment call: free-lift weigh-off to the required ascent rate for the station's requirement (usually 300-400 m/min), radiosonde payload at the specified suspension length below the balloon, radiosonde initialized and surface check values within calibration limits before the launch window opens. Launch from the upwind side of the station to clear the building obstructions. Post-launch: confirm signal acquisition and data flow on the ground-station software in the first two minutes, identify and log the surface and mandatory levels (1000, 850, 700, 500, 400, 300, 250, 200, 150, 100 mb and the tropopause), flag significant levels where temperature, wind, or humidity gradient change abruptly. A clean sounding is one where the mandatory levels are all captured and the significant levels are logged before the balloon bursts. Drill the procedure with the senior AG during a light observation day before you run one solo in the 0400Z window when the section is short-staffed.
  3. 03
    Plot a surface synoptic chart from coded FM 12 / SYNOP reports and identify basic features — fronts, pressure centers, isobars — clearly enough to describe the current synoptic pattern to the duty forecaster.
    Plot the station model correctly: sea-level pressure in the top-right position, temperature upper-left, dew point lower-left, wind direction and speed with shaft and feathers to the correct standard, sky cover circle shaded to the correct okta value, present weather in the correct position. Draw isobars at the correct interval, label them, find the centers. The front identification comes after the isobar analysis — the baroclinic zone, the wind shift, the temperature and dew point gradient across the line. Do not place a cold front where the isobar analysis does not support it because you think a front should be there. The duty forecaster will correct a misidentified front once and remember it at NWAE time. Practice plotting from the WMO surface reports that come into the station at the synoptic hours (0000Z, 0600Z, 1200Z, 1800Z) and have the AG2 walk the analysis with you before she constructs the official chart.
  4. 04
    Operate the primary weather station workstation — FNMOC/SPAWAR-issued system or current equivalent — and pull model guidance products for the duty AG2 without coaching.
    Know where the products live and how to navigate to them: synoptic-scale surface and upper-level analysis fields, model prognosis at the 24/48/72-hour intervals, satellite imagery in the visible, infrared, and water vapor bands, and the upper-air sounding comparison panels that let the duty forecaster see how the model guidance tracks against the observed soundings. The AGAN who can navigate to the model guidance fields, extract the requested fields at the requested valid times, and annotate or print the products without standing over someone's shoulder is the AGAN the duty AG2 can trust to set up the morning brief package before she walks into the watch room.
  5. 05
    Perform and document preventive maintenance on weather instruments — anemometer, barograph, hygrothermograph, radiosonde ground equipment — to the PMEL calibration schedule and METOC maintenance SOP.
    Every instrument on the PMEL schedule has a required maintenance interval and a required calibration check. The maintenance log entry must be complete — date, instrument identifier, maintenance performed, readings before and after, technician signature. Do not close an action without completing every step in the SOP, and do not close an action with a reading outside the calibration tolerance without flagging it to the duty AG2 for disposition. The AGAN who fast-forwards the maintenance log because the schedule is crowded is creating a systematic data quality risk under her name. The PMEL calibration audit that catches the undocumented discrepancy does not care that the day was busy.
  6. 06
    Maintain the NWAE study habit — BIB open, study log documented, AG3 advancement cycle tracked — from month one of the first assignment.
    Pull the current Bibliography for Advancement Exam Study from MyNavyHR for the current AG3 NWAE cycle on the first week of the first assignment. Build a study log in a notebook the LCPO can flip through: 30 minutes a day, four or five days a week, working chapter by chapter through the BIB references with margin notes. The exam covers the AG Rate Training Manual, the WMO observation standards, the OPNAVINST 3140.1 requirements, the NWP 1-03.1 doctrine, and the NAVPERS 18068 rate classification material. The AGAN who shows the LCPO a three-month study log earns study time on the watch bill; the AGAN who asks for study time the week before the exam is the AGAN who watches the slate from the bench.

Manuals & References — What Chapters Matter

  • OPNAVINST 3140.1 — Aerology
    The governing instruction for Naval aviation and surface force meteorological support. The AGAN needs to know the observation requirements by platform type, the product standards for each support category, and the reporting chain from the deckplate to the METOC officer. The sections on observation standards and product timeliness are the ones the duty AG2 quotes back at you when a product is late or a METAR is re-coded. Read it before your first watch-station qualification board.
  • WMO Technical Regulations, Volume I (WMO-No. 49) — General Meteorological Standards and Recommended Practices
    The international standard your METARs and SYNOP reports are encoded against. Chapter 2 (METAR/SPECI) and the appendices with present-weather codes are what you live in as an AGAN. The WMO standard does not change because the AGAN thought the ceiling might be higher. Know the present-weather table from memory by the end of the first three months on station.
  • WMO Guide to Instruments and Methods of Observation (WMO-No. 8)
    The technical reference for the instruments you maintain — anemometer, barometer, psychrometer/hygrothermograph, radiosonde system. The siting requirements, the calibration standards, the known error sources for each instrument type. The PMEL technician who calibrates your barometer knows this document; you should know the sections that touch your instrument suite before you sign the next maintenance log.
  • NWP 1-03.1 — Meteorological and Oceanographic Operations
    Navy doctrine for METOC support to naval operations. Read this to understand why the fleet commander cares about the forecast product your section produces, how METOC support is organized from NAVMETOCCOM to the deckplate, and what the fleet weather services command structure looks like. The AGAN who understands the operational purpose of the work does better observation discipline than the AGAN who thinks she is filling in weather forms.
  • AG Rate Training Manual (NAVEDTRA series) and the current AG3 Bibliography for Advancement (BIB) from MyNavyHR
    The BIB is the AG3 NWAE exam. Pull the current edition — not the one on the shared drive from a prior cycle. The NAVEDTRA rate manual covers the technical foundations (thermodynamics, atmospheric dynamics, observation methods, synoptic analysis, upper-air analysis) at the level the exam tests. Work through both together, using the BIB to prioritize the technical material and the rate manual to fill the gaps.
  • NAVPERS 18068 — Manual of Navy Enlisted Manpower and Personnel Classifications (rate classification and NEC entries for the AG rate)
    Read the AG-rate occupational standard and the NEC entries before your first career counselor meeting. The NEC catalog describes what the AGW and other METOC-related NEC codes actually mean in terms of billet type, school eligibility, and assignment pattern. The AGAN who walks into the NEC conversation without having read the source document spends the meeting learning what she should have known before she asked.

Standards — How to Hit Each

  • All observation PQS line items and watch-station qualifications signed off on the LCPO's timeline — the AGAN unqualified at six months is visible to the OIC.
    Walk the PQS book with the senior AG on watch during the first week. Identify the line items you can begin working immediately (surface observation encoding, instrument maintenance, station procedures) and the ones that require supervised evolution (rawinsonde launch, synoptic chart analysis). Ask the LCPO for the command's qualification timeline expectation on day one — do not assume there is no clock. Build a tracker in your notebook: line item, requirement, planned sign-off date, actual sign-off date. The AGAN who presents the LCPO with a completed PQS tracker at the four-month mark is the AGAN who earns the trust conversation.
  • METAR/SPECI encoding accuracy — zero systematic errors on the current observation when the duty AG2 spot-checks the product.
    Systematic errors are worse than random ones because they reveal a misunderstanding of the standard, not a momentary lapse. The most common systematic AGAN METAR errors: using FEW when BKN or OVC is warranted (underreporting the ceiling that the approach brief will use), rounding temperature to the whole degree instead of tenths, entering present-weather phenomena in the wrong order in the string, and failing to report significant changes between observation times as a SPECI. Have a senior AG spot-check your product during your first six observation shifts and tell you the category of any error, not just the correction. Fix the category of error, not the individual line.
  • Rawinsonde launch schedule met every assigned sounding — a missed mandatory upper-air observation is a gap in the fleet weather database.
    The sounding schedule is not flexible within the observation window. Pre-launch preparation starts at least 30 minutes before the launch window — balloon fill, payload attachment, ground equipment initialization, signal check. The AGAN who starts prep at T-10 minutes will miss or rush the launch, and a rushed launch with an unverified radiosonde initialization is worse than a documented missed launch because it introduces bad data without flagging the uncertainty. Build the pre-launch checklist into your watch routine and protect the 30-minute prep window on every assigned sounding shift.
  • PRT Good Low or higher; BCA in standard.
    Navy PRT cycles twice a year under OPNAVINST 6110.1. Pull the command PRT schedule on check-in and build the training plan around it — do not sprint to the test. The AGAN who fails PRT or BCA is flagged for a special-interval PRT and the LCPO's calendar reflects it. Good Low is the floor; Good Medium opens the advancement conversation; Outstanding is the AGAN the LCPO defends at the next ranking. The physical standard is visible in a small rating at a small command.
  • NWAE eligibility study habit established — BIB open and study log documented on the LCPO's timeline from the first month on station.
    The NWAE cycle for AG3 advancement will arrive within your first 12-18 months on station if your time-in-rate qualifies. The BIB study log is what the LCPO looks at when he is building the section's NWAE prep plan and the watch-bill study-time allocation. An AGAN with a documented 90-day study log earns study time on the watch bill; an AGAN who says 'I will start next month' on three consecutive LCPO check-ins is the AGAN who gets no allocated study time because the LCPO has stopped believing the plan.

Technical Mistakes — Concrete Consequences

  • Encoding a bad sky condition or ceiling height in the METAR because the ceiling was borderline and the AGAN chose the lower-workload code.
    The pilot planning the approach brief used that ceiling observation to determine whether the field was VFR or IMC at the planned recovery time. A wrong ceiling code is not a clerical error — it is an aviation safety event and it will come up in the post-incident review with the AGAN's name on the transmit log. The duty AG2 who approved the product without reviewing it also has her name on it, which is why the duty AG2 reviews every product before transmission — and why the AGAN who submits clean products earns autonomy faster than the AGAN who submits borderline ones.
  • Sending a rawinsonde sounding with an uncorrected sensor initialization error because the launch window was closing.
    A bad mandatory-level temperature or dew point at 500 mb feeds the FNMOC model guidance chain as truth. Every forecast center pulling data from that station's upper-air observation catalog is working with a bad input for the next 12-24 hours of model runs. The AGAN documents the error on the section log and notifies the duty AG2 before transmitting — even if it means a missed sounding. A documented missed launch with an explanation is professionally defensible. A transmitted sounding with a known bad sensor initialization is a data quality incident that traces back to the AGAN's name on the launch record.
  • Skipping a calibration or maintenance action on a PMEL-tracked instrument because the schedule looked flexible.
    Instrument accuracy is traceable. The PMEL calibration audit at the next scheduled interval will find the undocumented maintenance gap, and the technician's name on the previous maintenance log entry is the technician who closed the gap without completing the action. A barometer with an uncorrected offset produces systematic surface pressure errors in every METAR and synoptic report transmitted from the station until the error is caught. The duty AG2 who signed off on those observations eventually has the conversation with the LCPO about why the calibration log does not match the audit findings.
  • Relying on model guidance on-screen without cross-checking against the synoptic analysis or the most recent sounding.
    Model guidance runs wrong — model solutions diverge from reality, especially in mesoscale situations and over open ocean where data coverage is thin. The AGAN who stops looking at the sky, the sounding, and the synoptic picture and simply reports what the model says stops growing as a weather observer and starts becoming a model printer. The duty AG2 sees the pattern in how the AGAN describes the weather situation; the NWAE for AG2 tests whether the sailor understands synoptic patterns or can only read a model output.
  • Posting any METOC products, weather-system positions, or unit location details related to operational weather support on social media.
    METOC products in an operational environment — including products that describe the weather window for an underway replenishment, the flight-weather conditions for a carrier air wing's launch cycle, or the tropical weather threat to a fleet operating area — are operationally sensitive. Adversary collection services run social media sweeps looking exactly for this material. The OPSEC officer and the OIC sweep regularly. One post ends the clearance, the enlistment, and the NEC pipeline simultaneously. The AGAN who learns this after the post does not get a second chance.

Career Decisions at This Rank

  • Which unit type to request for the first follow-on assignment — shipboard aerology, METOC detachment ashore, air wing weather office
    The first duty station sets the career trajectory in a rating this specialized. Shipboard aerology on a deploying surface combatant or amphibious ship gives you operational intensity early — a small division, direct visibility to fleet operations, and the kind of forecast pressure that builds skill fast. The downside: the advancement study time competes with the watch bill and the sea-and-shore rotation starts immediately. Shore-based METOC detachment gives you a more structured training environment, more time for NWAE prep, and the AGW NEC pipeline access that the shipboard track may defer. Air wing weather at a naval air station puts you in the aviation-operations tempo — preflight brief cadence, fleet-weather-center product integration, and the aviation-safety culture that goes with supporting flight operations. Talk to AG2s who have done each before your first detailing conversation. The detailer moves fast; have a ranked preference list ready.
  • TSP enrollment — opt in to the 5% contribution to capture the government match or coast at the automatic 1%
    Every E-1 onward under the Blended Retirement System (BRS) gets the 1% automatic government contribution to TSP after 60 days of service. The 4% government match does not activate until you contribute at least 5% of base pay. The math at the AGAN paygrade over a 20-year career is not trivial — contributing 5% from E-2 onward means capturing the full match for the entire career. The AGAN who forgets to enroll at 5% in the first 90 days is the AG1 looking at a TSP balance materially smaller than it should be. Talk to the Fleet and Family Service Center financial counselor in the first 30 days. The conversation is free and the math is not optional.
  • First-term re-enlistment or ETS — the conversation that starts around 18-24 months in
    The AG rating is small and technically specialized, which means the SRB (Selective Reenlistment Bonus) and the career value of a well-stacked NEC are both real. Pull the current NAVADMIN for the AG SRB schedule before signing anything — the message is published and the numbers vary by NEC, zone, and rating manning. The honest version: the AGAN who re-enlists with the AGW NEC pipeline in motion and a clear follow-on billet has a different career package than the AGAN who re-enlists for the bonus and figures the rest out later. If the rating fits and the LCPO is recommending the path, the re-enlistment math usually works. If the only reason to re-up is the bonus and the job has not been what you expected, the bonus will not fix that problem.
  • AGW NEC pipeline vs. oceanography-support NEC vs. instructor duty — understanding the fork before it arrives
    The AGW NEC is the primary operational forecasting identifier in the rating — the billet code that goes with working forecaster assignments at METOC detachments, shipboard aerology divisions, and fleet weather support offices. Oceanography-support NECs within the NAVMETOCCOM enterprise are less visible to the junior AG community but exist and lead to different billet types. Instructor duty at 'A' school or C-school pipeline courses is a separate track that some AGs pursue at the HM2 or AG1 equivalent level. The AGAN who reads NAVPERS 18068 on the AG-rate NEC entries in the first year on station and has an informed question for the LCPO about the fork is the AGAN the LCPO invests in earlier. The AGAN who waits for the career counselor to explain the options at re-enlistment time is reacting, not planning.

How the Seat Varies by Unit Type

  • Ship's aerology division — surface combatant or amphibious ship (DDG, CG, LPD, LHD, LHA)
    A 3-5 person division on a small combatant or a slightly larger one on an amphib. Sea pay from day one. The OIC is the ship's meteorological officer (often a junior officer wearing multiple hats), the AG1 or AG2 is the watch-section lead, and the AGAN is in the observation rotation from week two. The operational tempo is determined by the ship's schedule — underway periods, exercises, deployments — and when the ship is underway the observation schedule is the primary reality. The forecast product goes directly to the captain's brief. Small-unit leadership visibility is high and the AGAN who performs well is known within three months; the AGAN who underperforms is also known within three months.
  • NAVMETOCCOM detachment or regional forecast center ashore
    A shore-based unit under the Naval Meteorology and Oceanography Command enterprise, running continuous forecast and observation support for an assigned fleet area or installation. More structured training schedule than shipboard duty, more time for NWAE prep and PQS sign-offs during garrison periods. The FNMOC product suite and the fleet weather center workflow are visible here in a way they are not always visible on a small ship. Larger section sizes mean more senior AGs to learn from, but also less individual visibility. The AGW NEC pipeline is often better supported at detachments with a dedicated training program.
  • Air wing or naval air station weather support office
    Weather support is the primary mission of the section and the preflight brief cadence drives the day. Flight operations are the clock — the morning brief window, the event weather packages, the divert-field forecast, the enroute and destination weather for every launch cycle. The aviation-safety culture is immediate and the consequences of a bad ceiling or icing call arrive the same shift. AGANs here learn the aviation weather product discipline faster than in any other billet type. The AGAN who is also comfortable with synoptic analysis and model guidance will be running morning brief prep within six months.
  • Joint METOC support environment (joint task force or combatant command METOC element)
    Less common at the AGAN tier but possible. Some NAVMETOCCOM support elements operate in joint environments alongside Army weather units and Air Force weather squadrons — the 1W0X1 pipeline the AG shares 'A' school with at Keesler. The joint METOC environment runs on joint doctrine (generally consistent with NWP 1-03.1 at the operational support level) and the AG's product standards and certification requirements remain Navy-sourced. The professional benefit is exposure to the joint weather support enterprise and the ASOS/AWS observation infrastructure the Air Force runs alongside the Navy METOC capability.

What Good Looks Like at This Rank

The good AGAN is the apprentice the duty AG2 trusts to take the 0000Z observation and the 0600Z sounding without a callback correction. Her METARs encode the sky condition correctly on the borderline cases — the ones where the ceiling is right at BKN height — because she goes outside and looks at the sky instead of defaulting to FEW because it is easier. Her rawinsonde pre-launch checklist starts 35 minutes before the window because she knows what happens when the initialization check fails at T-5 minutes. Her instrument maintenance log is current and every entry has both a pre-check and a post-check reading, because she read WMO-No. 8 on the barometer section and understood why the check exists before she performed it. The LCPO knows her name at the four-month mark because the duty AG2 mentioned her at section sync — not because of a problem, because of the PQS book that is more than halfway complete and the NWAE study log that is already in a notebook. By month eight the section officer has stopped including caveats when she describes the AGAN's observation products in the OIC brief. By month ten the AGAN is the one the duty AG2 asks to train the next AGAN in observation encoding, because the transmission log for the last four months shows zero systematic errors and one corrected borderline sky-condition call that the AGAN flagged herself before transmission. The career track conversation happens because the LCPO initiates it, not because the AGAN asked. The LCPO asks which world she wants — shipboard aerology on a deploying surface combatant, shore-based METOC detachment with the forecasting track and the AGW NEC pipeline, air wing weather support with the aviation-operations integration that goes with it, or the oceanography side within the NAVMETOCCOM enterprise. The AGAN who has already read the NAVPERS 18068 NEC entries and has a real answer to the question earns the career conversation that actually helps her. The AGAN who says 'I don't know yet' at the fourteen-month mark gets the career counselor's generic version and misses the LCPO's version.

Preview — The Next Rank

AG3 (E-4) is the first petty officer tier in the rating, and it arrives through the NWAE under the Navy Enlisted Advancement System — the Final Multiple Score (FMS) combining exam, eEVALs, time-in-rate, awards, and education. The cycle is twice yearly per the published NAVADMIN message; the cutoff is announced after each cycle. The AGAN who has built a documented BIB study log, closed the PQS book, earned the LCPO's recommendation in the eEVAL ranking, and is taking observations the duty AG2 does not have to correct is the AGAN who has a real shot. The AGAN who shows up cold watches the slate. The job at AG3 expands in two significant directions. First, forecast responsibility begins — not primary forecast ownership, which belongs to the AG2 and AG1, but forecaster-under-instruction assignments where the AG2 walks you through the synoptic analysis, the model guidance assessment, and the product construction under supervision. You begin learning to distinguish the model guidance solution that is tracking reality from the one that has gone off the observed trend, and you begin building the preflight brief skill under AG2 review. Second, you own a section of the watch bill in a more substantive way — you are no longer just the observation scheduler; you are the petty officer the AGAN looks to for sign-off direction and the AG2 trusts to have the morning brief package set up before she walks in. The PQS line items at AG3 cover the forecaster-under-instruction track, the preflight brief certification, and the senior observation qualifications. The NWAE for AG2 is no longer an abstract future event — it is the gate at the end of the AG3 tier and the AG3 who starts the BIB at the eighteen-month mark is already behind.
FAQ

AG E1-E3 — Frequently Asked Questions

Q01What does a E1-E3 AG (Aerographer's Mate) actually do?
Fresh out of AG "A" School at NAS Pensacola or Keesler AFB, you check into a Naval Meteorology and Oceanography Command (METOC) detachment, an air wing met unit, or a ship's aerology division and the AG2 hands you the observation schedule.
Q02What's the most important thing to know as a E1-E3 AG?
AG 'A' School runs at Keesler AFB (81st Training Wing) — joint with the Air Force 1W0X1 weather pipeline — and produces an AGAN who can take a surface weather observation and encode a correct METAR.
Q03What does a typical day look like for a E1-E3 AG?
Time-blocked day at the E1-E3 AG rank tier: 0500-0600 Wake up in the barracks or on-base housing. Quick check of the weather station status if you are on watch — any sensor alarms overnight, any PMEL calibration flags the duty section left on the log. PT gear on, walk or drive to the section gym or the command PT formation, 0600-0700 Command PT or section PT to OPNAVINST 6110.1 standard. At a METOC detachment or ship's aerology division PT is typically three days per week with the section; the other two days are individual PT time to the command schedule.…
Q04What mistakes get E1-E3 AG soldiers fired or relieved?
OPSEC breach on METOC products. METOC support in a deployed or operationally active environment produces products that are sensitive — fleet routing, aviation route weather, significant weather warnings for underway operations. One social media post with a product visible, a unit designation in the background, or a geotag near the operational area opens an OPSEC investigation that ends the clearance and the enlistment together;…
Q05What career decisions matter most at the E1-E3 AG rank tier?
Which unit type to request for the first follow-on assignment — shipboard aerology, METOC detachment ashore, air wing weather office — The first duty station sets the career trajectory in a rating this specialized. Shipboard aerology on a deploying surface combatant or amphibious ship gives you operational intensity early — a small division, direct visibility to fleet operations, and the kind of forecast pressure that builds skill fast. The downside: the advancement study time competes with the watch bill and the sea-and-shore rotation starts immediately.…
Q06What's next after E1-E3 for a AG (Aerographer's Mate) in the Navy?
AG3 (E-4) is the first petty officer tier in the rating, and it arrives through the NWAE under the Navy Enlisted Advancement System — the Final Multiple Score (FMS) combining exam, eEVALs, time-in-rate, awards, and education.
Q07What manuals and regulations does a E1-E3 AG need to know cold?
OPNAVINST 3140.1 — Aerology, provides the Naval aviation and surface force meteorological support requirements that govern every observation and forecast you produce.; WMO Technical Regulations, Volume I (WMO-No. 49) — the international surface and upper-air observation standards your METARs and RAOBs are encoded against.; NWP 1-03.1 — Meteorological Support to Naval Operations, the Navy doctrine document that defines METOC support concepts from deckplate to fleet commander.
