Short summary
A model was developed to derive night-time atomic oxygen (O(3P)) and atomic hydrogen (H) from satellite observations in the altitude region between 75 km and 100 km. Comparisons between the best-fit model and the measurements suggest that chemical reactions involving O2 and O(3P) might occur differently than is usually assumed in literature. This considerably affects the derived abundances of O(3P) and H, which in turn might influence air temperature and winds of the whole atmosphere.
