GPM Validation

GPM ground validation site Bonn

The Global Precipitation Measurement core satellite (GPM) operates with a Ku-band and Ka-band Dual-frequency Precipitation Radar (DPR). This is the first spaceborne DPR and allows important global insight into three-dimensional precipitation structures from space [1].

The polarimetric X-band research radar in Bonn, Germany, (BoXPol) is part of an international network for ground validation of the GPM satellite.
