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 Hurricane Imaging Radiometer (HIRAD) dataset contains ocean surface winds and precipitation observations from the HIRAD multi-band passive microwave radiometer. HIRAD uses novel interferometric aperture synthesis technique to produce high-resolution wide swath observations without any mechanical scanning of the antenna. The instrument was designed to measure ocean surface wind speed in tropical storms and hurricanes. Developed in collaboration between scientists and engineers at NASA MSFC, University of Central Florida and University of Michigan, the instrument was first flown on NASA high altitude aircraft in the Genesis and Rapid Intensification Processes (GRIP) Experiment in 2010 and Hurricane and Severe Storm Sentinel (HS3) in 2012-2014.
