Paper Abstract

Estimate is made of conditions which could lead to a possibility of solar radiation penetration to the Earth surface in the UV region. The altitude behaviour of the transmission for some frequencies is considered under variations of absorbing species concentrations. The value of the O2 absorption coefficient is diminished by a factor 10 for modelling the absorption in the transparency microwindows, therewith the ozone and water vapour content is varied. At variations of concentrations of absorbing species the transmission function of the solar radiation calculated from the upper bound of the atmosphere downward remains zero near the surface in microwindows of the Schumann-Runge bands. It appears, however, that near 210 nm the solar radiation may reach the surface at definite variations of concentrations of absorbing species.
