The Lower Stratosphere Mean Layer Temperatures (MLT) Climate Data Record (CDR) shows the long-term variation of Advanced Microwave Sounder Unit (AMSU) channel 9 brightness and Microwave Sounding Unit (MSU) channel 4 brightness measurements that peak in the Lower Stratosphere. These instrument signals are necessary to produce the monthly MLT of the Lower Stratosphere. Data (level-1b) from AMSU/MSU on board multiple satellites were calibrated using coincident Global Positioning System (GPS) Radio Occultation (RO) temperature profile measurements from 2001–present. The calibrated MSU/AMSU data from 2001–2014 serve as reference data to calibrate other overlapped MSU/AMSU data from 1980–2001. The final record has global coverage, and extends from 1986–2019.
