In the vertical, the model defines 90 atmosphere levels up to the maximum height of 75 km.Īt present, the model runs for forecast data distribution are at 00, 06, 12 and 18 UTC. The Guideline Transfer CDO is available at Open Data Weather – More information. The forecast data on a triangular grid can be interpolated to a regular (lat/lon) grid by using Climate Data Operators (cdo). The forecast data are also provided in standard packages on an icosahedral (triangular) grid. The grid structure of ICON is based on an icosahedral (triangular) grid of the earth's sphere. The ICON global model has been in operation at the DWD since.

The forecast data for each weather element (forecast parameters) are made available in standard packages at the free DWD Open Data Server. The numerical forecast data from all models are output in the GRIB2 format. ICON-D2 also provides ensemble forecasts. The DWD furthermore runs a regional model, ICON-D2, which is restricted to Germany and the neighbouring countries and is mainly used for very short-range forecasting. The newest in the DWD model suite is the global forecast model ICON (ICON = ICOsahedral Nonhydrostatic), with the higher-resolution ICON-EU nest for regional forecasts for Europe embedded in it. The DWD develops and runs several numerical weather prediction (NWP) models for global and regional forecasting.
