Attenuation due to rain at low elevation angles
Electronics Letters, 1977 Radar data on the reflectivity structure of rain showers were analysed to determine the dependence on elevation angle of attenuation statistics at 13 GHz on satellite propagation paths. For elevation angles between 10° and 30°, It was found that the attenuation occurring at a given probability level varied approximately with the cosecant of the ...
