ITU-R total attenuation predictions in comparison with slant path measurements in southern England

A simple method to obtain the total attenuation statistics from the statistics of different attenuation effects (gases, clouds, rain) is proposed and tested against measured data along with the current ITU-R methods. The new method based on a rigorous mathematical foundation and experimental observation gives a good agreement with experimental data and highlights the impact of atmospheric gases, cloud and light rain on earth-space systems operating at higher frequencies (Ka/V-band)
