Abstract
Simulation of the atmospheric transmission, using spectral line parameters from HITRAN-2008 database and CDSD databank, and the approximation of CO2 absorption line profile, taking the line-mixing effect of closely spaced lines into account, are carried out. For CO2 it is shown the characteristic examples of the spectral regions, where contribution of the effect is recommended to be taken into account in calculation of transmission in the atmospheric conditions.
