- Abstract
The problem of systematic overestimation (20-50%) of the retrieved ozone concentrations in the altitude range of 60-80 km in the TIMED-SABER satellite experiment in the daytime has been solved. The reason for overestimation is the neglect of the electronic vibrational kinetics of photolysis products of ozone and molecular oxygen O(bΣ , ν) and O(aΔ, ν). The IR emission band of O(aΔ, ν = 0) at 1.27 μm can be correctly used in remote sensing in order to obtain the ozone altitude profile in the altitude range of 50-88 km only with the use of a complete model of electronic vibrational kinetics of O and O photolysis products (YM2011) in the Earth's mesosphere and lower thermosphere. Alternative ozone tracers have been considered, and an optimum tracer in the altitude range of 50-100 km such as O(bΣ , ν = 1) molecule emissions has been proposed.
