Description

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) WFF data were collected during the Global Precipitation Mission (GPM) Ground Validation (GV) campaign at the NASA Wallops Flight Facility (WFF) in Wallops Island, Virginia. These data consist of the size, equivalent diameter, fall speed, oblateness, cross-sectional area of raindrops, particle concentration, total number of drops, total drop concentration, liquid water content, rain rate, reflectivity, and rain event characteristics. The data are in ASCII format and available from July 24, 2013 through October 5, 2015.
