GPM-GV Field Campaigns
The NASA Global Precipitation Measurement Mission (GPM) Ground Validation (GV) program, as a member of the broader NASA Precipitation Measurement Mission, is providing ground and airborne precipitation datasets supporting physical validation of satellite-based precipitation retrieval algorithms.
Field research campaigns are essential for observing and measuring actual Earth system phenomena and validating computer models that simulate Earth systems. Ultimately, field data help improve the nation's ability to predict climate change and its impacts. The collaborative effort between Earth Scientists at the Global Hydrology and Resource Center (GHRC) and IT researchers has resulted in unique solutions to the collection, archive, management and dissemination of science data.
