Abstract

We are presenting the results of astroclimatic studies in the North Caucasus started on our February 2020 expedition. The main objective of the studies is to compare millimeter-wave optical depth characteristics of four North Caucasus sites: BTA-6, RATAN-600, CMO of GAISh, and the Terskol Observatory. The opacity was studied by the atmospheric dip method in the 3 mm and 2 mm atmospheric windows. The astroclimate conditions of these four sites are compared through statistically processed data. This astroclimatic analysis has been performed with the view to selecting a site for radio astronomical observations in the millimeter bandwidth.
