The Two-Sample Model' predicts the probability distribution of rain attenuation a short time after a measured value, dependent on the values of two previous samples of rain attenuation. This model provides information on the dynamic behaviour of rain attenuation, useful for the design of FMT systems. Theoretical expressions have been developed to calculate the parameters of the Two-Sample-Model from rain rate measurements, dependent on meteorological parameters and link parameters. These expressions are compared to measurements of attenuation on a satellite link in the UK, and give good results on the long term. With this addition, the Two-Sample-Model parameters can be derived for different configurations using only rain rate measurements and other meteorological data. This will provide a great opportunity to assess the parameters on many sites on earth where expensive satellite link measurements have not been performed, facilitating the design of FMTs for these sites.
