Abstract

On the basis of the photochemical model for atomic oxygen [OI] 558 nm nightglow emission and an approximate expression for the altitude distribution of the atomic oxygen density in the MLT region at night, we develop a method for deriving the peak density of atomic oxygen in the MLT region from atomic oxygen [OI] 558 nm nightglow intensity. By using this method, the peak density of atomic oxygen is derived from the 558 nm airglow data received at the ISTP SB RAS Geophysical observatory in 2000-2004. The nocturnal variations and the seasonal variations of 558 nm airglow intensity and the derived peak density of atomic oxygen are considered. The results show that nocturnal variation of the 558 nm airglow intensity changes with season and that the monthly mean 558 nm airglow intensity changes with month, showing peaks in March, June and October, and larger values in the winter months The nocturnal and the seasonal variations of the peak density of atomic oxygen are generally similar to those of 558 nm airglow intensity.
