Scintillation is a phenomenon that affects microwave links and is still poorly modeled. Results of long-term measurements −5 years with almost 100% data availability-performed simultaneously from the same location at two different frequencies (Ka and Q-bands) in a converging link are presented here. The similarity of the time series of scintillation intensity in the two bands is commented. The variability of the standard deviation of the scintillation with the time of day on an annual basis and on a monthly basis is analyzed. Annual cumulative distributions are also presented and explored. The performance of some available models in the literature for scintillation amplitude is evaluated using locally measured meteorological data. The ITU model seems to slightly over predict the experimental results.
