Cloudy and Clear Sky Turbid UV Index and Dose Forecast


Forecasts of UV Index and erythemal effective UV dose

The German Meteorological Service (DWD) provides forecasts of erythemal effective UV based on the hourly results of DWD's global numerical weather predictions (ICON, pixel distance 13 km) and the non-hydrostatic European system (COSMO-EU, pixel distance 7 km). The calculations include ozone forecasts of the Royal Dutch Meteorological Institute (KNMI) and aerosol optical depth forecasts of the ECMWF, both provided as part of the Copernicus Atmosphere Monitoring Service (CAMS).
