Field notes are written automatically from AMPS, using rules from the Antarctic Weather Forecasting Handbook (Maitri and Novolazarevskaya). How they are written ↗
Field weather notes
the meteogram in words
Day by day wind, snow, cloud, temperature, pressure for each day
AMPS against the station reports

Temperature
Red: 2 m air temperature, daily highs and lows. Blue dashes: wind chill. Symbols every 6 h: clear, cloud or snow.
Cloud and snow
Grey: likely cloud by altitude (air saturated over ice; right scale). Orange ticks: cloud base. Blue bars: snow, mm of water per 3 h (about 1 cm of fresh snow per mm).
Wind
10 m wind in m/s (left) and knots (right). Arrows show where it blows to; letters, where it comes from. Dashed: strong (10 m/s) and gale (15 m/s). AMPS has no gusts.
Field weather notes
Amber: drifting snow (20 kt; 14 kt on fresh snow), snow of 0.5 mm or more, thick low cloud, a storm pattern, or a fast pressure fall. Red: blowing snow (35 kt) or whiteout risk. “Last run”: a hazard in two runs in a row is more reliable.
AMPS against the station reports
AMPS at Maitri compared with the Maitri reports (Novolazarevskaya shown too). A steady bias tells you how to read the charts, e.g. nights 2 °C too cold.
Pressure
Sea-level pressure. Red: a fall of 4 hPa or more in 12 h, often the first sign of a storm.
How this page works where the numbers come from
1. The model: AMPS
NCAR’s weather model tuned for Antarctica: 8 km grid, twice a day, 5 days ahead.
runs at 00 and 12 UTC, online about 10 h later2. An automatic job collects it
A GitHub job checks every 30 minutes while a run is due and downloads only the values at the grid points nearest the five sites (a few hundred kB).
09:00–12:00 and 21:00–00:30 UTC3. Charts and field notes
It draws the charts and writes the notes by fixed handbook rules, comparing each day with the previous run. Every rule and its source ↗
4. A check against real weather
It compares AMPS with the Maitri and Novolazarevskaya station reports (via Ogimet).
5. This page
The last 8 runs (4 days). Each site also links to meteoblue for a second opinion.
