Advanced Microwave Precipitation Radiometer (AMPR) IMPACTS

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Metadata Last Checked: August 10, 2025 | Last Modified: 2025-08-06
The Advanced Microwave Precipitation Radiometer (AMPR) IMPACTS dataset consists of brightness temperature measurements collected by the Advanced Microwave Precipitation Radiometer (AMPR) onboard the NASA ER-2 high-altitude research aircraft. AMPR provides multi-frequency microwave imagery, with high spatial and temporal resolution for deriving cloud, precipitation, water vapor, and surface properties. These measurements were taken during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) campaign. Funded by NASA’s Earth Venture program, IMPACTS is the first comprehensive study of East Coast snowstorms in 30 years. Data files are available from December 16, 2019, through March 2, 2023, in netCDF-4 format.
