Abstract

The estimation of errors in the longwave radiative fluxes simulation due to uncertainties in our knowledge of selective and continuum molecular absorption is presented. Modern models of the water vapour continuum absorption and different versions of the HITRAN spectroscopic database (2004, 2008, 2012) are used. It is shown that at present, the major source of the calculation errors in the longwave fluxes at cloudless atmosphere is still an uncertainty in the water vapour continuum absorption coefficients, while the contribution of line parameters’ errors to the simulation is relatively small.
