Millimeter-wave astroclimate studies in the North Caucasus: expedition and first results (original) (raw)

Fourth International Conference on Terahertz and Microwave Radiation: Generation, Detection, and Applications, 2020

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.
