cloud attenuation

cloud attenuation

[′klau̇d ə‚ten·yə′wā·shən]
(electromagnetism)
The attenuation of microwave radiation by clouds (for the centimeter-wavelength band, clouds produce Rayleigh scattering); due largely to scattering, rather than absorption, for both ice and water clouds.

However, strong scattering effects caused by the interaction between high frequency radiation and water droplets are not evaluated by cloud attenuation models, which are fundamentally based on the effects of radiation absorption, and not on scattering processes.
