Abstract
The use of the quasi-random band model in evaluating the upwelling atmospheric radiation is investigated. The spectral transmittance and total band absorptance are evaluated for selected molecular bands by using the line-by-line model, quasi-random band model, exponential sum fit method, and empirical correlations, and these are compared with the available experimental results. The atmospheric transmittance and up welling radiance have been calculated by using the line-by-line and quasi-random models and are compared with the results of an existing program called LOWTRAN. The results obtained by the exponential sum fit and empirical relations are not in good agreement with experimental results and their use cannot be justified for atmospheric studies. The line-by-line model is found to be the best model for atmospheric applications, but it is not practical because of high computational costs. The results of the quasi-random band model compare well with the line-by-line and experimental results. The use of the quasi-random band model is recommended for evaluation of the atmospheric radiation.
