Switzerland (CH)

9 of 10 data domains live

Switzerland rides the Alpine DACH stack — DWD ICON-D2 + ECMWF forecasts, Copernicus air quality + pollen — plus MeteoSwiss warnings (MeteoAlarm), EUMETNET OPERA radar (fully covered, incl. the Alps), METAR observations from 12 airports, a NOAA GHCN climate + historical archive (incl. high-altitude Säntis & Grand St-Bernard) and Swiss geocoding. Landlocked, so no marine domain — 9 of 10.
