Rain gauge data and also analysed fields from the diverse sources are assembled. For Berlin a high spatial resolution network combining observations by water authorities, DWD and own data is produced by the Free University of Berlin. The coordination project of the University of Bonn assembles data from several water authorities and environmental agencies and subsequently performs a quality check. The German Weather service contributes with its networks of online and climate stations. Based on these data analysed precipitation fields in 6-hourly (RANIE) and daily (REGNIE) resolution are available.
