Parameters of Absorption Lines of Water Molecules in the Spectral Region of 4500–4700 cm^–1

The absorption lines of the water molecule, broadened by atmospheric air pressure, were recorded in the region of 4500–4700 cm^–1 on an IFS 125 HR Fourier spectrometer. The parameters of the absorption lines of H₂O for the Voigt profile and the modified Voigt profile, including the dependence of broadening on the velocities of colliding molecules, were determined. Atmospheric transmission was calculated using the parameters of the absorption lines of H₂O from different versions of the HITRAN and GEISA spectroscopic databases and also using our new parameters of H₂O lines. Using our new parameters of the absorption lines of H₂O makes it possible to improve agreement between the model and measured atmospheric spectra.
