Models

The API serves the numerical weather prediction (NWP) and reanalysis models below. Pass the identifier in the model parameter. Each model exposes its own native (raw) variables plus a set of post-processed (harmonized) variables that share names and units across models (see Post-processed variables).

Spatial resolutions are the approximate native grid spacing of the source dataset and are provided for guidance; everything else (run frequency, horizon, availability, domain, variables) is taken from the live model registry and source classes.

Notable per-model behaviour:

  • ECMWF_ERA5 — backed by the Copernicus reanalysis class; supports the full harmonized set including WindGust (i10fg) and symbol.
  • ECMWF_ERA5-land — land-only; no CloudCover, PressureReducedMSL, or 100 m winds. RelativeHumidity is derived from t2m+d2m.
  • MeteoFrance_AROME-HD — high-resolution variant whose archive omits prmsl, ssrd and tp, so PressureReducedMSL, SolarDownwardRadiation, TotalPrecipitation and symbol are not available even though sibling AROME provides them.
  • Rebase_AI — AI model (GraphCast-based); no WindGust or symbol. 100 m winds, humidity, cloud and radiation are derived/diagnosed.
  • SMHI_MESAN — analysis product; no SolarDownwardRadiation or WindGust.

Model details

Each model below lists its native (raw) variables — the model-specific names you can request directly (in addition to the post-processed variables). Height/level variables use the Variable:height notation (e.g. Temperature_Height:80.0). Units are the model's native units; the post-processed variables convert them to common units. "Reference" links point to the ECMWF GRIB parameter database for the corresponding parameter.

Accumulated/averaged fields (precipitation, radiation) are totals or means since the start of the model run, not instantaneous values — the post-processing de-accumulates them.
