EXTPAR

EXTPAR (External Parameters for Numerical Weather Prediction and Climate Application) is used to prepare the external parameter data files that are used as input for the ICON model.

All information around this software can be found in the official EXTPAR documentation .

Support status

The master branch is continuously being tested on co2 (ETHZ) and levante (DKRZ).

Web Interface

Currently, C2SM, in collaboration with MeteoSwiss and DWD, is preparing a web interface for generating external parameter files on the ICON grid. A first beta version will be launched in March 2025.
