The Microwave Sounder Temperature Sounding Brightness Temperature (BT) – NOAA Climate Data Record (CDR) documents temperatures in the upper atmospheric layer. The Advanced Microwave Sounding Unit-A (AMSU-A) and the Advanced Technology Microwave Sounder (ATMS) instruments measure the mean temperature from a thick layer of the atmosphere using their channel weighting functions in satellite swath format (level-1b for AMSU-A, temperature data record (TDR) for ATMS).
Input consists of the AMSU-A raw counts data and ATMS TDR data from the Earth and blackbody views saved in the NCEI Comprehensive Large Array-data Stewardship System (CLASS) library. The period of record is 1998–present.
