TLDR
In this paper, a millimeter wave propagation experiment at 103 GHz (2.9 mm) on a propagation path of 390 m was conducted and the results were compared with the rain attenuation calculations from the Marshall-Palmer, Best, Joss-Thomas-Waldvogel and Weibull distributions for raindrop-size.Abstract:
We have conducted a millimeter wave propagation experiment at 103 GHz (2.9 mm) on a propagation path of 390 m. The results were compared with the rain attenuation calculations from the Marshall-Palmer, Best, Joss-Thomas-Waldvogel and Weibull distributions for raindrop-size. It has been shown that the Weibull distribution has a good agreement with the experiments.read more

Weibull Raindrop-Size Distribution and its Application to Rain Attenuation from 30 GHz to 1000 GHz
TL;DR: In this paper, a weibull raindrop-size distribution is fitted to the measurements of rainfall observed using a distrometer in Tokyo, and the rain attenuation is calculated by considering the Mie scattering for the Marshall-Palmer, Best, Joss-Thomas-Waldvogel, Gamma and Weibull distributions.

The size distribution of raindrops
TL;DR: In this article, the authors examined experimental data relating to drop size distribution in rain and showed that in many cases the size distribution is in accordance with the following formulae 1 - F = exp [-(x/a)n] a = A IpW = C Ir where F = fraction of liquid water in the air comprised by drops with diameter less than x.
