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 Atlantic Coast (2020-2022). The campaign aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The AMPR IMPACTS dataset files are stored in netCDF-4 format from January 18 through February 27, 2020. It should be noted that NASA ER-2 flights did not occur each day during the field campaign, therefore there are missing days between January 18 and February 27, 2020.GHRC Published AMPR IMPACTS Dataset
