The NASA Global Hydrology Resource Center (GHRC) DAAC published the Advanced Microwave Precipitation Radiometer (AMPR) instrument micro article. AMPR is a multi-frequency, dual-polarized, cross-track scanning passive microwave radiometer managed by NASA Marshall Space Flight Center (MSFC). AMPR measures microwave brightness temperatures at four calibrated microwave frequencies; 10.7, 19.35, 37.1, and 85.5 GHz. The microwave brightness temperatures observed at these frequencies can be used to derive cloud, precipitation, water vapor, and surface properties including ocean winds. The micro article provides an overview of the AMPR instrument and its applications to support GHRC’s current and future AMPR datasets. The micro article is available here:
