NOAA Climate Data Record for Mean Layer Temperature (Lower Stratosphere) from UCAR, Version 2

The Temperatures in the Lower Stratosphere (TLS) (AMSU channel 9 and MSU channel 4) CDR is generated by using National Oceanic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), and Europe METeorological Operational satellite-A (Metop/A) satellites which have been calibrated using coincident Global Positioning System (GPS) Radio Occultation (RO) temperature profile measurements from Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) and Challenging Mini-satellite Payload (CHAMP), and Gravity Recovery And Climate Experiment (GRACE) from 2001 to the current. The 'adjusted' MSU/AMSU data in the period of 2001 to 2014 were used as reference data to calibrate other overlapped MSU/AMSU data from 1980 to 2001.
