Abstract

According to the ground-based spectral observations of airglow emissions in the near infrared at Zvenigorod in 2000-2019, multi-year changes in the intensity of O₂A(0-1) band at 865 nm and OH(6-2) band at 840 nm are studied. It was shown that the intensities of both the emissions had a significant negative long-term time trend and a positive response to the change of solar activity in the 11-year cycle. In the spectrum of their interannual harmonic variations, statistically significant quasi-decade and quasi-two-decade oscillations were found.
