An analysis of the modern models of water vapour continuum absorption is carried out. The sensitivity of downward longwave fluxes to the continual absorption of water vapour is investigated. The spectral intervals, where the continuum absorption is the most significant, are defined. An analysis of recently discovered discrepancies between the models and experimentally measured absorption coefficients in the atmospheric transparency window of 8-12mm, is made. It is shown that these differences do not influence on the temperature dependence of continual absorption and the longwave radiative fluxes calculation realized in the Earth atmosphere.
