Advanced Microwave Precipitation Radiometer (AMPR) WHyMSIE

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 data were collected during the Westcoast and Heartland Hyperspectral Microwave Sensor Intensive Experiment (WHyMSIE) field campaign. WHyMSIE aimed to capture a wide variety of thermodynamic, moisture, and planetary boundary layer regimes across a variety of surface types. Comparing observations from AMPR, other instruments, and with in situ observations of temperature and humidity will allow for scientific advancement of remote-sensing techniques into the hyperspectral microwave era and improved understanding of the planetary boundary layer at different measurement scales. These data are available in netCDF-4 format from October 18, 2024 through November 13, 2024.
