Abstract. In this study, the new source of O(1D) in the mesopause region proposed by Kalogerakis (2019) is applied to SABER data to estimate the nighttime O(1D) distributions for the years 2003–2005. It is found that O(1D) evolutions in these years are very similar to each other. Depending on the month, monthly averaged O(1D) distributions may have a pronounced maximum (up to 80–110 cm−3 in January and July) localized in height (at ~ 97 ± 4 km) and latitude (at ~ 52 ± 4° S or ~ 52 ± 4° N). The nightly averaged O(1D) concentrations may reach ~ 300 cm−3. The obtained results are useful data set for subsequent estimation of nighttime O(1D) influence on chemistry of the mesopause region.
