The Dual-frequency Precipitation Radar (DPR) carried on the GPM Core Observatory satellite is the most advanced, accurate precipitation observing instrument applied the technology of the Precipitation Radar on board the Tropical Rainfall Measuring Mission (TRMM) satellite. The DPR brings a standard for various data acquired by the Core Observatory and constellation satellites conducted by the international cooperation partners. Integration of these calibrated data enables a global measurement of precipitation every three hours.
