Abstract. In the work using the GNSS method, monthly statistics of precipitated water vapor were obtained at new astronomical points in northeastern Eurasia: Hulugaisha Peak (Eastern Sayan), Kurapdag in the Agul District of Dagestan and the Tashanta checkpoint in the intermountain basin of the Altai Republic in comparison with the area of BTA, KGO and Terskol Peak Observatory. Changes in the hourly values of the median of precipitated water vapor at the Hulugaisha peak, the Tashanta APP and around BTA location are given according to the data of Era-5 reanalysis and moisture content in the surface layer according to meteorological data of 2023-2024. The collection of statistics of the optical thickness and precipitated water vapor in the area of BTA and new astronomical stations began with the help of a two-channel atmospheric radiometer IPAR-2 at a wave of 3 mm and 2 mm.
Keywords: submillimeter telescope, astroclimate, precipitable water vapor, optical thickness, radiometric method, GNSS method, Era-5 reanalysis.
Financing: This work was supported by the RSF grant N23-72–00041.
