Absorption of IR Radiation by H2O and Other Atmospheric Species. I. Dipole Autocorrelation Function for Far-Wing Pressure Broadening. II. Updating the AFGL Line Parameters Atlas for Asymmetric Rotor Molecules.

Abstract

In the first section of this report we describe a new approach for calculating the dipole autocorrelation function for molecular pressure broadening; the method satisfies the Fluctuation-Dissipation Theorem (FDT) on a microscopic basis. This is an important requirement for calculating far-wing molecular absorption. Tasks remaining for numerical implementation of the theory are also outlined and discussed. The second section describes procedures which have been developed to update the AFGL Line Parameters Compilation. The updating subroutines are documented, and a list of fourteen H2O bands to which the procedures has been applied is given. These bands have been incorporated into the 1980 Edition of the AFGL Atlas. (Author)
