摘要

Abstract: The recent in situ experiment by Vogelmann et al devoted to studies of the excess absorption to be for the clear humid atmosphere within the 0.94 $mu@m water band in the visible region shows that the problem of the absorption enhancement is caused rather by the uncounted molecular absorption into bands than by an aerosol absorption. On the other hand, our recent studies of the nonlinear continuum absorption of the pure water vapor had described the continuum absorption of the pure water vapor in the MW and IR. It is interesting to apply the nonlinear continuum, that is followed from the fundamental properties of the hypothetical absorption scattering interaction, to account for the absorption in the near IR region such as the band of 10400 - 10900 cm$+$MIN@1$/. The observed enhancement of 5 - 10% in comparison with a method using the Lorentzian is calculated and this is a result of the influence of UV bands of nitrogen on the selective continuum of the pure water. In a whole, the approach developed earlier has been successfully extended to the foreign broadening case.!12
