The Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) has published another core dataset in the Hurricane and Severe Storm Sentinel (HS3) collection. The HS3 High-altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) dataset contains precipitation and wind measurements from the dual-frequency, dual-beam, conically scanning radar that has been designed for the Global Hawk. HIWRAP's dual-wavelength operation enables it to map full tropospheric winds from cloud and precipitation volume backscatter measurements, derive information about precipitation drop-size distributions, and estimate the ocean surface winds using scatterometry techniques.
