The results of a preliminary analysis of the data on the global distributions of temperature and trace constituents in the middle atmosphere (15-65 km) obtained with the limb IR monitor (LIMS) are presented. The 6-channel limb-scanning radiometer was sensitive to the 15 micron bands of CO2, as well as other wavelengths, and was launched on the Nimbus 7 satellite in 1978. The derived data were partially compared with Soviet rocketsonde data to track an evolution in a warming trend over Siberia. The morphology of the changes were attributed to stratospheric warming. The comparisons with rocketsonde data indicated that the LIMS data were suitable for the determination of planetary wave amplitudes and phases, heat and momentum transport, and Eliassen-Palm fluxes.
