A Wide Band Model for the Absorption Coefficient Cumulative Distribution Function of Water Vapor and Carbon Dioxide

The parameters for the 1.38, 1.87, 2.7 and 6.3 micron bands of water vapor are developed for a wide range of pressures and temperatures from 300 K to 2900 K. The parameters for the rotational band of water vapor include temperatures from 300 K to 1900 K. Band parameters for the 2.0, 2.7, 4.3, 9.4, 10.4 and 15.0 micron bands of carbon dioxide are developed over a similar range of pressures and temperatures. The results obtained with this simplified model are in good agreement with existing narrow band and line-by-line results. The explicit formulation of the absorption coefficient in terms of the wide band cumulative distribution function represents an efficient and accurate method for use in complex radiative transport problems.
