A simple parameterization of infrared cooling between altitudes of 30 and 70 km consists of the sum of the exact cooling for a reference temperature profile and a Newtonian cooling approximation for departures from this profile. The parameterization is developed by using the 1962 standard atmosphere for the reference temperature. The exact line-by-line calculation of cooling gives total infrared cooling rates that in the vicinity of the stratopause are somewhat greater (∼1 deg day−1) than the values obtained by previous investigators, apparently because the present study includes ‘second hot bands’.
