Abstract

The revised model of excited OH with constants corresponding to the published data was applied to retrieve daytime O and H distributions at 77 km–100 km from the data of the SABER/TIMED satellite measurements in 2002–2021. It was found that changes of parameters in the retrieved procedure lead to (1) a noticeable (up to 30%) increase of the O concentration below 85-86 km, (2) a significant (up to 170%) increase of the H concentration below 90 km and a moderate (up to 40%) decrease near 100 km. The influence of revised O and H data on the retrieval of OH and HO2 is also analyzed.
