Tuned Diode Laser Measurements of Atmospheric Absorption Profiles in the 4.5 micrometers to 5.0 micrometers region.
Abstract
This report describes results obtained from infrared spectra of H2O and CO2 in the 4.8 micrometers region taken with a tunable diode laser. For CO2, evidence is given for the inclusion of an additional term in the F-factor over that usually used in the case of the main 4.8 micrometers band. In the case of H2O, strength measurements are compared with the AFGL line parameters, as well as with calculations of Camy-Peyret and Flaud, with the present study supporting the latter. Limited data is also presented on investigations of line widths, self-to-foreign broadening coefficients and line shapes for water vapor. In addition to these results, a method is proposed which should enable the measurement of the far wing shape of a line without the need of considering overlap from other lines.
