International audienceIn this paper, we present a methodology to compare frequency scaling techniques of rain attenuation. This methodology consists in obtaining rain attenuation from beacon measurements, selecting a subset of events, and applying metrics on the obtained time series. Are also discussed methodologies to separate the contributions of clouds and rain to attenuation, as well as a method to identify events affected by noise. The relevance of the approaches is evaluated on a database of satellite beacon attenuation: Italsat beacon measurements from Spino d'Adda (7 years)
