Abstract

The calculation of transmission for a model spectrum requires the adoption of a distribution function for line intensity. In the case of the infrared water-vapor spectrum (random model), a logarithmic ogive distribution for line intensity is very realistic and produces smaller transmission and cooling-rate errors than other functions previously proposed. These results apply also when experimental data are assumed available and the requisite parameters are obtained by curve fitting.
