Abstract :
Analysis of amplitude scintillations in an 11.5 GHz SIRIO-Earth link has been performed. The intensity of scintillations has been evaluated for July 1984 by means of scintillation index. The hourly values of this index have been compared to the ground temperature measured in a site close to the vertical projection of the path. Both scintillation index and temperature seem to follow a similar cyclical behaviour. The relationship between the number of occurrences and the value of the index is also represented, together with a two-segment linear-wise approximation.
