Abstract :
A physical structure model is utilized to analyze the frequency dependence of the adjustment factor associated with empirical attenuation models for earth-space paths. The frequency dependence seen in empirical models comes in part from the frequency dependent specific attenuation. Melting layer and cloud attenuation that is inherent in the data give rise to significant frequency dependence at higher exceedance probabilities.
