Suomi NPP ATMS Sounder Science Investigator-led Processing System (SIPS) Level 1B Brightness Temperature V3 (SNPPATMSL1B)

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/fcxkuue9vcln

The Advanced Technology Microwave Sounder (ATMS) Level 1B data files contain brightness temperature measurements along with ancillary spacecraft, instrument, and geolocation data of the ATMS instrument on the Suomi National Polar-orbiting Partnership Project (SNPP).

Description

The ATMS instrument is a cross-track scanner with 22 microwave channels in the range 23.8-183.31 Gigahertz (GHz). The beam width is 1.1 degrees for the channels in the 160-183 GHz range, 2.2 degrees for the 80 GHz and 50-60 GHz channels, and 5.2 degrees for the 23.8 and 31.4 GHz channels.

Since the SNPP satellite is orbiting at an altitude of about 830 km, the instantaneous spatial resolution on the ground at nadir is about 16 km, 32 km, or 75 km depending upon the channel. The brightness temperature data are contained in an array with 135 rows in the along-track direction, 96 columns in the cross-track direction, and a 3rd dimension for each of the 22 channels. The ATMS cross-track scan interval is 0.018 seconds and the along-track scan period is 8/3 seconds.

Data products are constructed on six minute boundaries. The ATMS (Advanced Technology Microwave Sounder) and CrIS (Crosstrack InfraRed Sounder) instruments are meant to operate together as a system, thus providing coverage of a much broader range of atmospheric conditions. The ATMS-CrIS system is referred to as CrIMSS (Cross-Track Infrared and Microwave Sounder Suite).
