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.

¹ ECMWF_HRES_OPERATIONAL delivers the latest HRES run without the standard delay; ECMWF_HRES_MIX blends the historical archive with the latest operational run. Both support point queries only (no grid/area).

Post-processed variable availability

WS covers both WindSpeed and WindSpeed:10; WD covers WindDirection and WindDirection:10 (the 10 m value is produced once and exposed under both names).

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.
