Method of Calculating H20 Transmission Between 333 and 633 cm-1.
Abstract
Spectral absorption data are presented for H2O between 1/333 cm and 1/633 cm. An empirical continuum has been determined to account for all of the absorption not attributed to absorption lines centered within approximately 1/30 cm of any wavenumber of observation. The empirical continuum, which consists of one part for self broadening of the H2O lines and one part for N2 broadening, has been determined experimentally for three temperatures: 296K, 338K and 430K. Other values based on extrapolation have been determined for lower temperatures representative of the atmosphere. A line-by-line calculation scheme involving the empirical continuum and the AFGL line parameters has been used to calculate spectra for several samples investigated in the laboratory. The calculated spectra agree quite well with the laboratory spectra. (Author)
