AIMR
in scheme: instruments
definition: The Airborne Imaging Microwave Radiometer operates from the NCAR/NSF C-130 aircraft, scanning across the flight track through the nadir point. The instrument measures surface and atmospheric radiation emissions at 37 and 90 GHz. Each frequency is separated into horizontally and vertically polarized channels. To date, the instrument has primarily been used for mapping of the polar ice cap (ice and snow change their radiative properties with age) but potential may exist for mapping ground moisture content as well.
