GPM Ground Validation (GV) efforts include the direct statistical validation and verification of satellite estimates against high-quality ground measurements and physical validation for algorithm improvement and hydrological models.
Provide calibrated ground-based precipitation measurements and associated error characterizations at 50-km horizontal resolution for comparison with space-based radar and radiometer measurements at designated ground validation sites within ground tracks of the GPM Core Observatory.
Tokay, 2016: A novel approach to identify sources of errors in IMERG for GPM ground validation.
To support prelaunch algorithm development and postlaunch product evaluation, NASA has established a broad range of joint projects with domestic and international partners to use ground-based observations (including aircraft measurements) to conduct the following three categories of ground validation (GV) activities:
In addition to NASA-sponsored campaigns, NASA has also participated in a number of leveraged field campaigns of opportunity: the CloudSat/Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Ground Validation Program (C3VP) field campaign in the winter of 2006/07 to collect data for snowfall algorithm development (Hudak et al.
