The dataset measures mean layer atmospheric temperatures from the lower-troposphere to the lower-stratosphere. The dataset was inter-calibrated and merged from three generations of microwave sounders, MSU, AMSU-A, and ATMS, with 16 polar-orbiting satellites including TIROS-N, NOAA-6, NOAA-7, NOAA-8, NOAA-9, NOAA-10, NOAA-11, NOAA-12, NOAA-14, NOAA-15, NOAA-18, NOAA-19, MetOp-A, Aqua, SNPP, and NOAA-20. The dataset includes temperature mid-troposphere (TMT, MSU channel 2 merged with AMSU-A channel 5 and ATMS channel 6), temperature upper-troposphere (TUT, MSU channel 3 merged with AMSU-A channel 7 and ATMS channel 8), temperature lower-stratosphere (TLS, MSU channel 4 merged with AMSU-A channel 9 and ATMS channel 10), and temperature lower-troposphere (TLT, derived from combinations of TMT, TUT, and TLS). TLT, TMT, TUT, and TLS measure layer temperatures peaking roughly at 3km, 5km, 10km, and 17km, respectively, above the Earth's surface. Features in the dataset development include a use of backward merging approach, development of an observation- and semi-physically-based algorithm for diurnal drift adjustment, and removal of spurious calibration drifting errors in NOAA-15, NOAA-14, NOAA-12, and NOAA-11 through recalibration. Satellite microwave sounding observations in stable sun-synchronous orbits (Aqua, MetOp-A, SNPP, NOAA-20) were used as a reference in the backward merging process. Bias corrections and satellite recalibration have resulted in inter-consistent CDR records for reliable climate change investigation. The dataset was and will continue to be used for detecting and monitoring the long-term climate trends in the atmospheric temperatures. The dataset has been broadly used by the climate science community, the general public, and decision makers for understanding the long-term climate trends in the past and climate change projections in the future. The dataset is a key dataset, owing to its global coverage, to provide climate change information and help the society to make appropriate policy decisions on climate change mitigation and adaptation.

It removed inter-satellite biases in historical satellite observations on and before the dataset submission date. However, satellite drifts may occur with satellite aging, causing bias drifting errors in future satellite observations. As a result, cautious views are recommended on the climate trends obtained from the operational products. When in doubt, it is recommended to contact the dataset developing team for information on the calibration of satellite observations after the dataset submission date. otherRestrictions Cite as: Zou, Cheng-Zhi; Hao, Xianjun. 2023.
