Definition

  • The MSU is the descendant of the Scanning Microwave Spectrometer (SCAMS) flown on Nimbus-6, which in turn evolved from the Nimbus-5 Microwave Spectrometer (NEMS). NEMS was the first microwave temperature sounder flown in space. The MSU is a four channel Dicke radiometer making passive measurements in regions of the 5.5-mm oxygen region (50.3 GHz, 53.74 GHz, 54.96 GHz, and 57.05 GHz). The dynamic range of the MSU is 0 K to 350 K, with a noise equivalent temperature of 0.3 K. The ground resolution at nadir is 109 km; the swath width is 2347.2 km. The MSU, flown on the Advanced TIROS-N (ATN), was used in conjunction with the SSU and HIRS/2 as part of the TOVS package (see the sensor reference for TIROS OPER VERTICAL SOUNDER). _________________________________________________________________ Entry taken from: Rao,P.K., S.J.
