GPM ATMS on NOAA-20 Common Calibrated Brightness Temperatures L1C 1.5 hours 17 km V08 (GPM_1CNOAA20ATMS) at GES DISC

Version 08 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 08.

1CATMS contains common calibrated brightness temperature from the ATMS passive microwave instrument flown on the Suomi NPP satellite and JPSS satellites. ATMS is approximatly a combination of the AMSU-A channels and the MHS channels, to the total of 22 channels. ATMS rotates 3 scans per 8 seconds. 1CATMS contains 4 swaths, one for each band K, A(Ka), W, and G. ATMS geometric footprints are: 75km x 75km (23-32GHz), 32km x 32km (50-90GHz), 16km x 16km (165-183GHz). GPM Project cross-calibrates channels at spatial sampling: 23.8, 31.4, 88.2, 165, and 183 GHz at 16x16 km.
