GPM GROUND VALIDATION HIGH ALTITUDE IMAGING WIND AND RAIN AIRBORNE PROFILER (HIWRAP) IPHEX V1

The GPM Ground Validation High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) IPHEx dataset was collected during the Global Precipitation Measurement (GPM) Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign in North Carolina. The goal of IPHEx was to evaluate the accuracy of satellite precipitation measurements and use the collected data for hydrology models in the region. The NASA ER-2 aircraft flew during the IPHEx field campaign to aid in GPM validation. The science instruments, including the HIWRAP, onboard the aircraft acted as a proxy for GPM satellite instruments. HIWRAP is a Doppler radar that combines conical scan mode measurements at two different frequency bands (Ka- and Ku-band) and two different incidence angles (30 and 40 degrees). Twenty-one ER-2 flights occurred from May 1, 2014 through June 14, 2014. The HIWRAP dataset includes netCDF-4 files containing radar reflectivity and Doppler velocity profiles along with aircraft altitude and other navigation information.
