The NASA Global Hydrology Resource Center (GHRC) DAAC published the Advanced Microwave Precipitation Radiometer (AMPR) IMPACTS dataset. This datasets consists of passive microwave observations at four frequencies; 10.7, 19.35, 37.1, and 85.5 GHz. With high spatial and temporal resolution, AMPR can derive cloud, precipitation, water vapor, and surface properties. This dataset was collected during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) for the IMPACTS field campaign. HIWRAP 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 (Ka- and Ku-band) and two different incidence angles (30 and 40 degrees). HIWRAP utilizes solid state transmitters along with a novel pulse compression scheme resulting in a system that is considerably more...
