The Advanced Technology Microwave Sounder (ATMS) is a cross-track microwave sounder that combines the capabilities of current generation microwave temperature sounders (Advanced Microwave Sounding Unit, AMSU-A) and microwave humidity sounders (MHS) that are flying on EUMETSAT’s and NOAA's IJPS satellites. It measures at 22 frequency bands in the range from 23GHz through 183GHz. Check the JPSS pages on the NOAA website for more details.
The provision of ATMS data in the form of an EARS-service is a logical extension of the EARS-ATOVS service, providing operational sounder data with high timeliness for the assimilation in numerical atmospheric models from regional to global scale.
