TLDR
In this paper, a modification in the rain attenuation model taking into account the melting layer height variation with the season and rain rate was proposed, which may not be valid for tropics.Abstract:
Hydrometeors pose a serious threat to satellite communication operating above 10 GHz. The designing line of sight link usually is based on the ITU-R models, which are often inadequate for tropical region. ITU-R model uses a yearly averaged constant rain height for the attenuation calculation, which may not be valid for tropics. This paper reports the study of rain height based on Micro Rain Radar and Radiosonde observations at two tropical locations in Indian region. Results suggest a possible modification in the rain attenuation model taking into account the melting layer height variation with the season and rain rate.read more

Analysis of bright-band height data from TRMM-PR for satellite communication in Durban, South Africa
TL;DR: Comparison of the observed results show that the International Telecommunication Union - Recommendation (ITU-R) P.839 recommended values were underestimated, and recommends using the physical information about rain height derived from the local databases to improve in the rain attenuation prediction accuracy for this region.

Analysis of the moments and parameters of a gamma DSD to infer precipitation properties: A convective stratiform discrimination algorithm
TL;DR: In this article, a new method of moments was developed and tested to determine the three gamma DSD parameters, which are less sensitive to the underestimation of small drops in the JW disdrometer, and validated by comparing the observed rainfall rates with the computed ones from the fitted distribution, using two classical expressions for the hydrometeor terminal velocity.
