Abstract

A description of the atmospheric effects on electromagnetic-wave transmission is obtained by modeling the attenuation due to water vapor, oxygen, rainfall, snow, clouds, and dust. The technique developed for calculating the attenuation due to dust is an extension to that used for calculating the attenuation due to rainfall, and it seems to be valid. Calculation of the attenuation was done at 10 GHz and can be extended to the other frequencies of the microwave spectrum. It is shown that dust has a significant effect on transmission, especially in desert regions. The attenuation due to dust cannot be ignored in places with dust storms, where the attenuation increases as the number of dust storms increases.<>
