Advanced microwave precipitation radiometer

This paper describes the development and preliminary testing of an imaging passive microwave radiometer operating in the 10 to 85 GHz range specifically for precipitation retrieval and mesoscale storm system studies from a high altitude ER-2 aircraft. The instument is referred to as the Advanced Microwave Precipitation Radiometer (AMPR). The primary goal of AMPR is the exploitation of the scattering signal of precipitation at frequencies near 10, 19, 37, and 85 GHz to unambiguously retrieve precipitation and storm structure intensity information in support of space sensors, as well as, storm-related field experiments onboard the ER-2 in 1989/90.
