Attenuation - Continued

  • Can't really correct for attenuation, it is basically ignored in most cases - one hopes that it is not a large problem

  • Attenuation is worse for shorter wavelengths - here is an example of attenuation from a 3 cm radar.

  • Hail attenuates the worst, then heavy rain, then snow, then cloud drops, then atmospheric gases (about 2 dB per 100 km, indeed small)
