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

Statistical Analysis of Rain at Millimeter Waves in Tropical Area
TL;DR: The measured rain rate and rain attenuation distributions are analysed and benchmarked with several previous measurements and well-known prediction models and showed that the best agreement between the measured rainfall rate in Malaysia and the ITU-R PN is shown.

Rain Attenuation at Terahertz
TL;DR: Rain attenuation values were calculated using empirical raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R, and showed that the propagation experiment was in very good agreement with this calculation.

Comparison of Experimental and Theoretical Determined Terahertz Attenuation in Controlled Rain
TL;DR: In this article, the effects of rain attenuation on 0.1-to 1-THz frequencies were reported, where the THz pulses propagate through a rain chamber over a 4m distance and are measured by THz-TDS.

Terahertz wireless communications
TL;DR: This chapter describes the motivation for terahertz wireless communications, the effect of atmospheric propagation, modeling of communications channels, and hardware, and the goal of this chapter is to provide a comprehensive review of wireless terAhertz communications for which tera hertz waves are the free-space carrier of data.

Secrecy performance of terahertz wireless links in rain and snow
TL;DR: The theoretical investigations on physical layer security of a point-to-point terahertz link in rain and snow with a potential eavesdropper locating outside of the legitimate link path find that the THz link suffers least eavesdropping attacks inRain and the maximum data transmission rate decreases for higher carrier frequencies in rain.

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.
