Time invariant data preprocessor for the climate version of the COSMO model (COSMO-CLM)

The PrEProcessor of time invariant parameters required for the boundary data definition in the COSMO-CLM is described. PEP incorporates the present preprocessor from DWD and gives additional access to the geospatial information provided by the ECOCLIMAP data. It processes various global geospatial data into spatial resolution and into rotated coordinates system specified by the user. Available global topography, land cover as well as soil characteristics datasets are reviewed and their use in various processing options of PEP is presented.
