Abstract:
Absorption coefficient of H2O broadened by N2 in the spectral range 9450-9475 cm-1 is calculated using line-by-line method with different empirical and theoretical expressions for the spectral line shape. The comparison made between the calculated data and those obtained in laboratory and field measurements shows that a good agreement between the calculated and laboratory measurement data on the absorption coefficient can be achieved by changing the line contour. However, to explain measurement results obtained in a dry cloudless atmosphere one should take into account some additional factors different from the molecular absorption.
