High Altitude MMIC Sounding Radiometer (HAMSR) EPOCH V1

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Catalog Last Checked: June 23, 2026 at 08:55 PM | Dataset Last Updated: June 22, 2026
The High Altitude MMIC Sounding Radiometer (HAMSR) EPOCH dataset includes measurements gathered by the HAMSR instrument during the East Pacific Origins and Characteristics of Hurricanes (EPOCH) project. EPOCH was a NASA program manager training opportunity directed at training NASA young scientists in conceiving, planning, and executing a major airborne science field program. The goals of the EPOCH project were to sample tropical cyclogenesis or intensification of an Eastern Pacific hurricane and to train the next generation of NASA Airborne Science Program leadership. HAMSR has 25 spectral channels which are split into 3 bands to provide measurements that can be used to infer the 3 dimensional distribution of temperature, water vapor, and cloud liquid water profiles in the atmosphere, even in the presence of clouds. HAMSR is mounted in payload zone 3 near the nose of the Global Hawk NASA aircraft. Data is available from August 9, 2017 through August 31, 2017 in netCDF-3 format.
