AB: The Sounding of the Atmosphere using Broadband Emission Radiometery (SABER) instrument operating on the Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED) satellite provides, among other parameters, measurements of ozone and atomic oxygen in the mesosphere. Specifically, daytime ozone is derived from measurements of the molecular oxygen airglow at 1.27 um. Ozone is also derived day and night from measurements of ozone emission at 9.6 um. Both of these emissions are in non-LTE and the non-LTE retrieval algorithms will be reviewed. Comparisons we will present of the daytime ozone retrieved from both techniques provide an important internal consistency check of the ozone measurements. SABER ozone measurements can also be used to derive atomic oxygen in the mesosphere using various photochemical relationships between ozone and atomic oxygen in the daytime. At night, the SABER hydroxyl emission measurements provide a measure of atomic oxygen. The combination of these measurements yields the global distribution of odd-oxygen in the mesosphere.
