Abstract

The H₂O absorption lines broadened by air pressure were recorded using Bruker IFS 125 HR Fourier spectrometer in the 5900-6100 cm^–1 spectral region. The intensities, broadening and shift coefficients of H₂O absorption lines were retrieved for lineshape profile taking into account a dependence of the broadening on collision molecules speed. The atmospheric transmission was calculated with use of H₂O line parameters from the HITRAN spectroscopic database and our data. A comparison with the atmospheric solar spectra measured using a ground-based Fourier spectrometer was carried out.
