Monochromatic Transmittance/Radiance Computations
Abstract
A computer program and associated procedures have been developed to compute high resolution spectra for inhomogeneous optical paths including both atmospheric conditions and conditions typical of a missile plume. These programs and procedures are outlined in this report. The procedures have been used with the Air Force Cambridge Research Laboratories line atlas to demonstrate that ignoring the correlation of atmospheric absorption lines with source emission lines can lead to errors as high as 79 percent for some spectral bands and optical paths. Calculated spectra have been compared with experimental laboratory spectra typical of both atmospheric and missile plume conditions. The AFCRL line atlas requires the addition of lines from highly excited states and the correction of certain inadvertent errors to be applicable to the calculation of high temperature optical properties of gases.
