GPM GROUND VALIDATION PRECIPITATION VIDEO IMAGER (PVI) GCPEX V1

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Catalog Last Checked: August 04, 2026 at 11:09 PM | Dataset Last Updated: June 22, 2026
The GPM Ground Validation Precipitation Video Imager (PVI) GCPEx dataset collected precipitation particle images and drop size distribution data from November 2011 through March 2012during the GPM Cold-season Precipitation Experiment (GCPEx). Data files in an Excel format contain the average, minimum, and logarithmic drop size distribution bin sizes and number of particles. Browse images are available online. The PVI instrument was designed by Dr. Larry Bliven at NASA Wallops Flight Facility.
