The NASA Global Hydrology Resource Center (GHRC) DAAC published the High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) instrument micro article. The HIWRAP instrument is a Doppler radar designed to measure tropospheric winds through deriving Doppler profiles from cloud and precipitation volume backscatter. The winds are generated by combining conical scan mode measurements at two different frequency bands and incidence angles. HIWRAP has flown science flights on the NASA high-altitude (20 km) Global Hawk Unmanned Aerial Vehicle (UAV) and the NASA ER-2. The instrument is able to measure the tropospheric winds above heavy rain at high levels. HIWRAP has also been used to study precipitation microphysics as well as precipitation characterization and process studies. This micro article provides an overview of HIWRAP and its applications to support current and future GHRC publications.
