  5. Microwave imaging instrument on AQUA • Advanced Microwave Scanning Radiometer (AMSR) • Conical scan geometry • Main dedication is integrated atmospheric properties, soil moisture, sea surface temperature, sea ice, and wind • 6, 10, 18, 23, 37, 89 GHz • All channels dual polarization • Spatial resolution varies with frequency between 6 x 9 km and 70 x 50 km
