Temperature dependence of molecular absorption in the atmospheric transparency window at 340 GHz

Recent laboratory measurements made by Furashov and Katkov (1985) confirmed that the nonlinearity of air humidity dependence of the atmospheric water vapour absorption coefficient in the transparency windows centred at 340 and 410 GHz exceeds essentially the theoretical one which is associated with the self-broadening of H/sub 2/O monomer spectral lines. Data testifying to a stronger dependence of absorption on the temperature at 340 GHz in comparison with that calculated for monomers are presented.
