Increased use of computer models in environmental applications requires spatial analyses of meteorological parameters as input fields. MeteoSwiss is currently developing procedures for the generation of gridded km-scale meteorological analyses for the territory of Switzerland based on data from its operational observation networks. This presentation gives an overview of recent developments with a focus on methods and datasets for precipitation. The various developments address different user needs, ranging from climate monitoring to hydrological forecasting. Two methods for real-time precipitation analysis will be discussed in some detail. The first is Reduced Space Optimal Interpolation (RSOI), which is based on a multivariate statistical linkage between coarse real-time and dense climatological station measurements. The second is an adaptation of geostatistical concepts for the real-time combination of radar and station measurements. The presentation illustrates that innova
tive combination of different observation platforms can provide considerable added value and address some of the challenges in a region of complex terrain.
