December 1978 - March 2006

The MSU temperature data are provided by John Christy of the University of Alabama Huntsville ( christy@atmos.uah.edu ) and Roy Spencer of the National Aeronautics and Space Administration Marshall Space Flight Center ( roy.spencer@msfc.nasa.gov ).

Three MSU temperatures are available:

Temperature anomaly maps for individual months can be viewed through this link. You will need to select "stratosphere" on the display to see the MSU LS maps. I'm not sure if the "troposphere" maps are TLT or TMT.

A large variety of phenomena can be studied with this data, for example the Quasi-Biennial Oscillation (QBO) and sudden stratospheric warmings. In the following, the dominant patterns of variability are documented in emiprical orthogonal functions (EOFs, spatial patterns) and associated principal components (PCs, amplitude time series) of correlation and covariance matrices of MSU LT, MT, and LS are presented.
