The capabilities of the calculated approach for the astroclimatic assessment in radioastronomy
ABSTRACT
The work is dedicated to calculation of daily variability of monthly averaged full vertical at-mospheric absorption for six well-known moun- tain locations of sub-millimeter wave band ra-diotelescopes obtained with usage of chosen by authors models combination. Test locations we- re defined as follows: Chajnantor plateau in the Atacama mountain desert (Chile), Hanle (India), South Pole (Antarctic), Mauna Kea (Hawaii, USA), Sierra Negra (Puebla, Mexico) and El Leoncito (Argentine). The data of these calculations were compared with the data of long term radiometric observations of other authors. Se- arching for new alternative places to complement existing sub-millimeter telescopes locations was attempted too.
