We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

GPM GV - UConn
Global Precipitation Measurement Ground Validation Campaign at the University of Connecticut
NASA's Global Precipitation Measurement (GPM) Ground Validation (GV) field campaign at the University of Connecticut (UConn) is an ongoing project that measures frozen precipitation and its characteristics.
The goal of this field campaign is to provide an unprecedented dataset of wintry precipitation observations from multiple traditional and novel precipitation measurement instruments. This dataset can be used for validating NASA GPM products, to examine the error characteristics of co-located ground-based instruments, or to investigate microphysical properties of snow crystals. This unique set of measurements can be used by researchers for snow microphysics or remote sensing applications.
The instruments deployed include an assortment of K-band and W-band profiling radars and Ka-Ku band scanning radars; weighing and tipping bucket pluviometers; laser and video disdrometers; high-speed and high-resolution cameras for quantitative precipitation measurement; weather stations; and an unmanned aircraft system for environmental variables.
