In the framework of the Hans-Ertel-Centre for Weather Research (HErZ), the University of Bonn, the University of Cologne and the German Meteorological Service (DWD) are cooperating in the research area Climate Monitoring and Diagnostics. The major goal of this consortium is the continuous development and evaluation of a self‐consistent assessment and analysis of regional climate in Germany and Europe. It encompasses the synergetic use of heterogeneous monitoring networks to construct state‐of‐the‐art regional reanalysis data sets.
These regional reanalyses provide quality‐controlled and homogenized data sets as a basis for the detection and assessment of regional climate change in past and future, the development of applications in various fields as well as the verification and calibration of impact models like e.g. hydrological models.
Currently, two major regional reanalysis data sets have been made available for Continental Europe and Central Europe at horizontal resolutions of 6km and 2km, respectively. While the research group and its partners are further developing the regional reanalysis systems in multiple projects, work for generating derived fields by the application of post-processing methods to the regional reanalysis data sets are also under way with post-processed solar radiation fields for COSMO-REA6 already available.
