Summary:Summarizes the measured sand/dust storm parameters and its effect
on the radio links. Nine sand storms were experienced in the city of
Riyadh during 1987, and were observed both by the meteorological sensors
and by the radio links. The measurements were used to determine the
prominent storm parameters which have considerable effects on wave
propagation into such storms. Such parameters include particle
concentration, particle size and size distribution, and refractive index
of such particles, or its dielectric constant. As the moisture content
of sand/dust particles increases, attenuation increases markedly. The
measured attenuation, as the millimetricwaves propagate through sand
storms, is compared with the calculated value of attenuation. Such
calculated attenuation is found by using an attenuation model which
relates attenuation to visibility, frequency and particle size and
refractive index
