Incomplete Gamma Function Approximation for King's Strong-Line Transmittance Model.
Abstract
An approximation to the incomplete gamma function is presented for use with King's model for strong-line molecular transmittance through gases in the infrared. The approximating function circumvents computational problems inherent with the infinite series representation of the incomplete gamma function or of its derivations. A mean transmittance deviation from the series of 0.0002 is obtained over the range of variables of interest in atmospheric applications.
