Temperature dependence of molecular atmospheric transmission function in field of 2--400 {micro}m and the earth radiation balance
The global climate change problem becomes actual by the end of the 20th century. Its many important aspects are: the change of molecular composition of the earth`s atmosphere (in particular, the accumulation of CO{sub 2}, CH{sub 4}, SO{sub 2} in the atmosphere), and the problem of ozone layer depletion. This paper is devoted to the investigation of fundamental mechanisms of the atmospheric transmission function influence, in the field of 2--400 mm and especially in the range of windows 8--13 mm and 3--4 mm, on the thermal balance of the earth`s atmosphere. The negative and positive feedbacks between the absorption of the outgoing heat radiation in the atmosphere and the heating of the earth`s surface have been considered. All the simulations of the infrared radiation transfer are based on spectral data from GEISA-92 data bank. Temperature dependence of molecular transmission function has been obtained and three steady states for earth`s radiation balance were shown to exist. A radiation balance regime, leading to closing of the atmospheric window 8--13 mm and development of the explosive greenhouse effect has been obtained and discussed in this paper.
