AB: The SABER instrument on TIMED measures the limb radiance in ten broadband infrared channels for an altitude range that includes the mesosphere and lower thermosphere. In this altitude range the effects of non-local thermal equilibrium (non-LTE) must be included to understand the measurements. The non-LTE algorithms and computer code package developed to analyze CRISTA infrared spectral limb radiances were adapted for this purpose. We retrieved temperature profiles from the 15 μm limb radiances measured in the summer 2002 polar mesopause. The retrieved temperature profiles will be compared with other retrievals, the coincident falling sphere experiments of the MaCWAVE campaign, and climatological data. Sources of the discrepancies between the various results are discussed.
