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
