Multi-frequency Dual-polarized Platform for Validation of Satellite Precipitation Measurements
Abstract: Satellite missions such as the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) mission have demonstrated the value of rainfall measurements at a global scale. Both missions use a multi-frequency suite of instruments to achieve their measurement goals. Calibration and validation of these instruments have a vital role in the success of the mission since they strive to characterize precipitation quantitatively. The work presented focuses on results obtained and proposes future steps in support of GPM and future missions within the context of ground validation (GV). Results are based in the development and deployment of a ground-based Ku/Ka-band, dual-polarized, Doppler radar in support of the GPM GV efforts, while future steps define instrument additions/upgrades deemed valuable for GPM GV or future missions.
