GPM GROUND VALIDATION HIGH ALTITUDE IMAGING WIND AND RAIN AIRBORNE PROFILER (HIWRAP) MC3E V1

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Metadata Last Checked: February 21, 2026 | Last Modified: 2026-02-17
The GPM Ground Validation High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) MC3E dataset was collected by the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP), which is a dual-frequency (Ka- and Ku-band) conical scan system, configured with a nadir viewing antenna on the high-altitude (20 km) NASA ER-2 aircraft. It provides calibrated reflectivity and unfolded Doppler velocity. The GPM Ground Validation High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) MC3E dataset consists of netCDF (.nc) files and images (.gif). Measurements included within the data files are merged pulse and chirp radar reflectivity profiles at 13.9 and 33.7 GHz.
