It is the successor to the Advanced Microwave Sounding Unit (AMSU) on NOAA weather satellites.
[6] Also, ATMS continues the record from its predecessor instruments MSU and AMSU of measurements in the 5-mm band of oxygen for monitoring of atmospheric temperature trends.
[7] All of the channels are contained within one unit, unlike the AMSU which comprises two instruments (AMSU-A and AMSU-B).
[1] The sampling rate satisfies the Nyquist criterion for channels 1-16; thus, images produced from the data are not aliased.
[1] However, ATMS images exhibit striping, attributed to receiver gain fluctuations (1/f noise),[2] which can be removed by filtering the data.
