The datasets are described in the document "Information Regarding Synthetic Microwave Sounding Unit (MSU) Temperatures Calculated from CMIP-3 Archive". Potential users should download and read this document before downloading the datasets. No additional documentation nor additional support for these data can be provided.

Publications using any or all of the synthetic MSU T₂ temperatures and/or the synthetic T_2LT temperatures should reference these datasets as follows:

"Synthetic MSU temperatures from 49 simulations of 20^th century climate change were calculated as described in Santer, B.D., et al., 2008: Consistency of modeled and observed temperature trends in the tropical troposphere. International Journal of Climatology, 28, 1703-1722, doi:10.1002/joc.1756."

The datasets are available as two GZIP archives of 49 ASCII files each. Open source utilities to extract the files from the archive on computers running the Windows and UNIX operating systems are available at http://www.gzip.org. File extraction was tested using the commercial software package WinZip (http://www.winzip.com) on a Windows XP computer system.
