The Sounding of the Atmosphere using Broadband Emission Radiometery (SABER) is one of four instruments on NASA's TIMED Mission. SABER is a broad-band limb scanning radiometer that measures infrared emission from atmospheric species between 10 and 280 km tangent point altitude. One of the SABER channels is centered at 1.27 μ m where the O2(a1∆ g-- X3σg-) Infrared Atmospheric band emission dominates the atmospheric airglow. In the sunlit mesosphere, direct production of O2(a1∆ g) during solar photolysis of O3 in the Hartley band is the major source of this O2 emission and atmospheric ozone abundances between 60 and 90 km can be deduced from the measured O2(1∆ g) volume emission rates using a simple photochemical model. We have inferred the daytime O3 abundances between 60 and 90 km using SABER measurements taken during the period January 25 2002--January 24 2003. In this paper the derived O3 concentrations are presented and compared with those obtained from other observations and predictions by photochemical models.
