NOAA Climate Data Record of Microwave Sounding Unit (MSU) Mean Atmospheric Layer Temperature, Version 1.2 (Version Superseded)

Published by DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 20, 2025 | Last Modified: 2014-06-11T00:00:00.000+00:00
*Note: This dataset version has been superseded by a newer version. It is highly recommended that users access the current version. Users should only use this version for special cases, such as reproducing studies that used this version.* The dataset contains three MSU channel-based, monthly gridded atmospheric layer temperature Climate Data Records generated by merging nine NOAA polar orbiting satellites, TRIOS-N and NOAA-6 through NOAA-14. These are temperatures of middle-troposphere (TMT), upper-troposphere (TUT, also known as temperature troposphere stratosphere), and lower-stratosphere (TLS), corresponding to measurements from MSU channels 2, 3, and 4, respectively. These products have global coverage with a 2.5 latitudes by 2.5 longitude grid resolution. Time period is from November 1978 through September 2006. Adjustments of observations included limb-adjustment, diurnal drift corrections, warm target temperature effect, and residual inter-satellite bias removal.
