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).
