Paper Abstract

In the work an analysis of possible errors of the longwave radiative fluxes calculation due to spectroscopic uncertainties of HITRAN2004 database lines parameters and continuum models is carried out. Upper estimations of the fluxes calculation errors are founded. The errors are 0.2% for downward and 0.25% for upward fluxes. It is shown that the uncertainties of water vapor continual absorption may cause the fluxes error more then 1%, that exceeds the line parameters error. A comparison of the radiative fluxes calculated with different continuum models used in radiative codes is made.
