Abstract:

During the period of the contract, the AFCRL report AFCRL-TR-73-0096, by McClatchey, Benedict et al., summarizing the preparation of the extensive data tape containing over 100,000 atmospheric absorption line parameters, was issued. Activity under the contract was principally devoted to the detection and correction of inaccuracies in the tape and the report, and to the extension of the data base. For water-vapor, new higher energy levels were obtained from the umbral and flame spectra and the analysis of the absorption in the visible region was advanced. For CO2, improved new spectra of Venus and Mars provided more accurate rotational constants for some of the lower vibrational levels of the isotopic forms, and additional very weak bands were measured for the first time. Progress was made in the analysis of the combination bands of methane in the 2800cm and 4300cm regions. Isotopic bands of ammonia were measured and analyzed. The present report will give a brief summary of the above activities, with particular emphasis on the water-vapor analysis in the visible region.
