Effect of meteorological conditions on scintillation fading in the oxygen absorption region.
The effect of the absorption mechanism on the amplitude of the scintillations on a 4-km line of sight link at 54.5 GHz in different meteorological conditions is examined. When atmospheric temperature turbulence is dominant, the absorption mechanism causes the amplitude of the scintillations to be significantly increased for the large outer scale of turbulence sizes. When water vapor pressure fluctuations begin to dominate, the enhancement of the scintillations is suppressed, and the effect of the absorption mechanism on the amplitude scintillations is minimal.
