Abstract:

The NASA band model formulation for calculating the radiance and transmission of gases is evaluated by comparing its predictions to laboratory data on H2O, CO2, and various mixtures containing these gases. The calculations reproduce the measured values for homogenous and inhomogeneous samples of H2O to within about or - 20. The agreement with measured values for CO2 was not as good, especially at low pressures. The theoretically derived band model parameters for CO2 appear to be in error. For mixtures of H2O, CO2 and other gases N2, CO, H2, the agreement was good. Author
