AB: The TIMED Satellite was launched on December 7, 2001 to study the dynamics and energy of the mesosphere and lower thermosphere. The SABER instrument is a limb scanning infrared telescope designed to measure minor atmospheric constituents as well as temperature and pressure of the region. In this study we have concentrated on data retrieved for the polar mesosphere, to investigate spatial and temporal temperature characteristics of this region. We made the comparisons between the winter and summer, and studied both short- and long-term variability in different quadrants of each hemisphere. The sharp transition between summer and winter, first demonstrated using falling-sphere meteorological rocket data, will be described for each hemisphere with a data base including variations in many geophysical parameters. Differences in this climatological base between 2002-2004 will also be discussed.
