Abstract : The basic elements of line by line prediction of atmospheric transmittance at infrared wavelengths, and the quantum mechanical bases of line parameter computation are reviewed. A FORTRAN IV(G) computer program using the AFCRL Atmospheric Absorption Line Parameters Data Compilation tape for high resolution transmittance prediction under homogenous conditions is presented together with running instructions. An analysis of the effects of the using collisionally narrowed line profiles rather than simple Lorentzian profiles is also included, and suggests that collisional-narrowing may be significant with certain types of transmission paths.
