The Consortium for Small-Scale Modelling(COSMO) - Model is a non-hydrostatic limited-area atmospheric prediction model. It has been designed for both operational numerical weather prediction (NWP) and various scientific applications on the meso-B and meso-y scales. The COSMO-Model is based on the primitive thermo-hydrodynamical equations describing compressible flow in a moist atmosphere. The model equations are formulated in rotated geographical coordinates and a generalized terrain following height coordinate. A variety of physical processes are taken into account by parameterization schemes.The present operational application of the model within COSMO is mainly on the meso-B scale using a grid spacing of 7 km. The key issue is an accurate numerical prediction of near surface weather conditions, focusing on clouds, fog, frontal precipitation, and orographically and thermally forced local wind systems. The COSMO-Model provides two kinds of output: The results of the forecast can be written in GRIB or in NetCDF output. For more information about COSMO - Model, please refer to the web-site: www.cosmo-model.org(and its mirror: cosmo-model.cscs.ch).

Operational COSMO-Kenya is based on GME data.

NB: The COSMO-Model is available free of charge for scientific and educational purposes, especially for cooperational projects with COSMO members. However, all users are required to sign an agreement with a COSMO national meteorological service and to respect certain conditions and restrictions on code usage. For questions concerning the request and the agreement, please contact the chairman of the COSMO Steering Committee. In the case of a planned operational or commercial use of the COSMO-Model package, special regulations will apply.
