Applications in a wide range of disciplines require quantitative precipitation analyses at high spatial and temporal resolution with near real-time availability. To meet these needs, MeteoSwiss has developed, in an internal research project (CombiPrecip), three prototypes for generating km-scale, hourly precipitation analyses by real-time combination of radar and rain gauge information. The present study evaluates and compares these methods systematically in order to provide the scientific basis for the implementation of an operational system for such analyses at MeteoSwiss
