Description

The GPM Ground Validation Reference Precipitation IPHEx dataset consists of 10 years (December 31, 2007-December 31, 2017) of hourly rainfall intensity at 1 km2 resolution over the core region of the Integrated Precipitation and Hydrology Experiment (IPHEx), that is centered in the Pigeon River Basin in North Carolina. The goal of the IPHEx field campaign was to evaluate the accuracy of satellite precipitation measurements and use the collected data for hydrology models in the region. Data files are available in ASCII format.
