AB: We examine the global morphology of mesospheric inversion layers (MILs) using the unprecedented temperature database derived from the SABER instrument on the TIMED satellite which so far covers the period 2002 to mid 2004. The 100 percent duty cycle of the SABER instrument allows us to get nearly global coverage of temperature profiles from 52S-83N (or 83S-52N in the opposite phase of the yaw cycle). With this data we have catalogued the occurrence and amplitude of inversion layers as a function of local time and latitude for equinox and solstice. For each season we use data from an entire yaw cycle (about 62 days) in order to cover all local times. Preliminary results show a large occurrence frequency of MILs with amplitudes of greater than 20K (at equinox) with the largest amplitudes and highest occurrence rates in the equatorial region. We correlate the occurrence of MILs and their amplitude with the expected tidal phase and amplitude and map the horizontal extent of the larger MILs.
