Abstract:

The results of studies of the precipitable water vapor (PWV) at Terskol, Kislovodsk, Nauchny, Sheki, and Hunzakh sites are presented. The comparative analysis of changes in GNSS-derived PWV and PWV estimated from the ERA-5 reanalysis database has been performed. The ERA-5 data make it possible to reveal new sites suitable for millimeter/submillimeter telescopes. In view of the comparatively low total cloud cover, Rutulsky and Agulsky regions are the most promising for building millimeter/submillimeter telescopes in the North Caucasus (Dagestan, mt. Horai (3521 m), Kаtаlnats (3780 m), mt. Karah (2876 m), and mt. Sindaky (2849 m)).

Keywords:

telescope, astroclimate, precipitable water vapor, ERA-5 database, GNSS, GPS, satellite geodesy
