| Abstract: |
Cosmic factors, like solar activity, solar wind and geomagnetic activity strongly influence the upper atmosphere-ionosphere, while galactic cosmic rays have an impact on the lower atmosphere. These factors are to be taken into account in the atmospheric models. We investigated the long-term atmospheric observational data carried out in Abastumani Astrophysical Observatory (N41° 45'; E42°49') in connection with different cosmic factors. In this study we consider the inter-annual variations of the upper atmosphere parameters, in particular, the atomic oxygen 557.7 nm green, 630.0 nm red lines of the nightglow, as well as those of the number of cloudless days and nights as the parameters of cloud covering in the lower atmosphere. The annual and semi-annual variations in the green and red line intensities, as well as in the numbers of cloudless days and nights at different helio-geophysical conditions were found. |
