The capabilities of the calculated approach for the astroclimatic assessment in radioastronomy

Earth atmosphere causes considerable impediments for radioastronomical observations at millimeter and sub-millimeter waves bands due to atmosphere attenuation and instability its transfer function. Consequently, even a slight improvement of the transfer function and its stability can lead to a tangible radioastronomical observations efficiency increase, especially in the submillimeter wave range. In view of this and taking uniqueness and high cost of the radiotelescopes that are installed in various regions of the world, location astroclimatic suitability assessment is required. These assessment are usually experimental and consist of gathering the statistical information concerning the extent of atmospheric attenuation, it´s seasonal and daily unsteadiness to reveal the most favorable time and place for the observation to be performed.
