Globally gridded precipitation-data sets are an essential base for various applications in the geosciences and especially in climate research, as for instance global and regional studies on the hydrological cycle and on climate variability, verification and calibration of satellite based climate data or the evaluation of global circulation models (GCM’s). As all these applications require reliable high quality precipitation fields the underlying station data have to meet high demands concerning the quality of the observed precipitation data as well as the correctness of station meta data and also with respect to sufficient spatial station density and distribution. Concerning the use of globally gridded climate data for analyses of long-term climate variability it has to be ensured that station-data used for gridding are as continous and homogeneous as possible.
