A parameterization of the cooling rate of the Earth’s atmosphere in the height region of approximately 20-75 km due to radiation transfer in the 9.6 μm O3 band is proposed. A general random band model is used to calculate the radiation transmission. The parameterization takes into consideration a peculiar feature of the radiative transfer-the height step increases with growing distance from the level for which cooling is calculated. A simple method of accounting for the variation of the vertical profile of the absorbing gas is proposed and utilized. The procedure proposed is multiparametric: 22 parameters are prescribed for calculating cooling at a given level. The procedure can be recommended for calculating radiative cooling for any temperature and ozone profile not having a small- or meso-scale structure. It can be used, in particular, for modelling of the middle atmospheric circulation. © 1985.
