Tashanta as a promising astropoint of the Altai mountains: the first results of the astroclimate study

For the Tashanta point, 49°43ʹ4ʺN, 89°11ʹ31ʺE, Gorny Altai, data from continuous measurements of astroclimatic parameters of the surface layer, monthly average values of the total cloud cover, suspended water vapor from the ERA5 atmospheric reanalysis database and primary measurements of the altitude distribution of turbulence are presented. The results show unique astroclimatic and operational conditions, which probably make it one of the best places in the Russian Federation for submillimeter and optical range observatories.
