This paper reports the statistical relationship between 1 s averaged rain attenuation (A, in decibels) and standard deviation (, in decibels) of simultaneous tropospheric scintillation in 1 s intervals, derived from high resolution (50 samples/s) experimental 12.5 GHz attenuation time series recorded at Spino d'Adda (45.4°N) in a 30.6° slant path to satellite Olympus during an observation time of approximately 1 year. The statistical relationship can be fitted by the power law derivable from a thin turbulent layer model. A similar relationship was also previously obtained in the same slant path at 19.77 GHz. As a consequence, we have concluded that at least up to 20 GHz, the modeling is independent of frequency.

Abstract

This paper reports the statistical relationship between 1 s averaged rain attenuation (A, in decibels) and standard deviation (, in decibels) of simultaneous tropospheric scintillation in 1 s intervals, derived from high resolution (50 samples/s) experimental 12.5 GHz attenuation time series recorded at Spino d'Adda (45.4°N) in a 30.6° slant path to satellite Olympus during an observation time of approximately 1 year. The statistical relationship can be fitted by the power law derivable from a thin turbulent layer model. A similar relationship was also previously obtained in the same slant path at 19.77 GHz. As a consequence, we have concluded that at least up to 20 GHz, the modeling is independent of frequency.
