The Airborne Multichannel Microwave Radiometer (AMMR) measures
thermal microwave emission (in degrees Kelvin of brightness
temperature) from surface and atmosphere. The up-looking
radiometer at 21 and 37 GHz is a component of AMMR that was
developed in the 1970's for precipitation measurements from an
aircraft. The entire AMMR assembly covers a frequency range of
10-92 GHz. The 21/37 GHz unit has been flown in many types of
aircraft during the past three decades in various field
campaigns. It was refurbished during the year 2000 and is ready
for flights again.
