Abstract :
The prediction models for scintillation variance of ITU-R and Karasawa et al. (1988) are compared to measurements on a time base which is much shorter than originally considered for these models. It is shown that even after averaging over just three days, a good correlation with the measured variance is found. Both models predict higher scintillation variance than is measured at 19.8 GHz on a 12.7° elevation path in Kirkkonummi, Finland
