The statistical regional climate model WETTREG has been used to simulate today's and future climate of Germany for different climate scenarios (IPCC). The simulations have been initiated by Umweltbundesamt (P. Mahrenholz) and performed by CEC Potsdam GmbH / Meteo-Research (W. Enke). The WETTREG simulation starts 1961 and calculates the today's and future climate from 1961 to 2100 using the ECHAM5/OM IPCC control and scenario run 1 (SRES A1B, A2 and B1) in T63 horizontal resolution as boundary condition. For all variables time series on daily basis are available. The model domain covers Germany. The dataset is based on station data. There is no transient run. For each decade 200 year of simulations were calculated. The output is separated for each German state and parameter. Berlin is added to Brandenburg, Hamburg to Schleswig-Holstein, Bremen to Niedersachsen and Saarland to Rheinland-Pfalz. For the parameter rainfall the file is separated in climate (RR) and rainfall (RX) stations. The RX file for Bayern and Hessen is separated into two files (BY and BA; HE and HS). For each parameter 3 files were saved. File 1 contains the first 100 years, file 2 the second 100 years and file 3 examples for a dry, wet and normal 10 year period. Standard output format for all data is ASCII (semicolon separated values). All data are saved in 1/10 off the given unit. Missing values are set on -9990.
