Abstract
The database of the SABER/TIMED satellite campaign includes the reconstruction results of nighttime distributions of O, H, and some other characteristics at heights of the mesosphere–lower thermosphere from measurements of volume emission rate ofOH* profiles near 2 μm, temperature, and ozone. The retrieval procedure is based on the chemical equilibrium approximation of nighttime ozone and a model of two excited OH states (ν = 9.8) forming the indicated radiation. In this work, a modernized model of these levels with the corrected constants corresponding to published data is used to retrieve O, H, OH, HO2, and the chemical heating rate at altitudes of 80–100 km according to SABER/TIMED measurements in 2002–2021. It is found that the new parameters of the retrieval procedure lead to significant (up to 2 times or more) changes in the spatial distributions of O, H, and chemical heating rate, but only a slight change in OH and HO2 distributions.
期刊介绍：
Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
