The Scanning Multichannel Microwave Radiometer (SMMR) is a passive microwave radiometer measuring dual polarized microwave radiation from the earth's surface and atmosphere in 5 frequencies; 6.63, 10.69, 18.0, 21.0 and 37.0 GHz. SMMR Swath width is 600 km.
Global coverage was achieved within the orbital extremes: +77/-72 deg. latitude from July 7 - August 17, 1978 with a ground track equatorial spacing of 165 km. From August 18 - October 10, 1978 (the date that SEASAT terminally malfunctioned) the ground track equatorial spacing was 900 km. From July 7 to August 26, 1978, the ground track was repeated every 17 days. From August 27 to October 10, 1978, the ground track repeated once every 3 days. The measurement temporal resolution is 10/second.
This data set contains LEVEL 1b data consisting of calibrated information about the intensity of radiation emmitted from the sea in a microwave band. The parameter is calibrated brightness temperature. Output is in the form of calibrated Sensor Data Record Tapes.
Related data sets: Seasat SMMR (Levels 1a, 2) Altimeter (Levels 1a, 1b, 2) SASS (Levels 1a, 1b, 2) and VIRR (Levels 1a)
These calibrated Sensor Data Record tapes are available from the JPL DAAC. The JPL DAAC holds the complete Seasat data set.
