Abstract
Results are presented for two years of satellite beacon and radiometric attenuation measurements on two 12 GHz Earth-space links located in Rio de Janeiro, south-eastern Brazil and Belem, northern Brazil. Results suggest that the choice of 285 K for the standard medium temperature, to be used in the calculation of attenuation from radiometric measurements of sky temperature, may underestimate the conditions for tropical and equatorial environments
