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

Service Aggregation in Motional Rainfall Cell Queues Over Wireless Radio Links
TL;DR: The concept of service aggregation of rainfall queues obtained from ground measurements is examined and suggests that - two or more parallel queue servers maybe present - at different strata in the troposphere during typical rain events at these sites.

Propagation-Impairments Modelling and Fade-Mitigation Techniques for Earth-Satellite Links
TL;DR: In this article , the authors discuss the effect of atmospheric effects on satellite-channel attenuation and compare the performance of site diversity and site-diversity-based attenuation techniques.

Doppler radar characteristics of precipitation at vertical incidence
TL;DR: In this article, a comprehensive review and extension of the theoretical bases for the measurement of the characteristics of rain and snow with vertically pointing Doppler radar are presented, where the drop size distribution in rain can be computed from the Doppher spectrum, provided that the updraft can be estimated, but difficulties are involved in the case of snow.

Electromagnetic Wave Propagation Through Rain
TL;DR: In this article, the effects of rain on weather and climate models are discussed, and an approach to attenuation mitigation via diversity via diversity is proposed. But this approach is not suitable for outdoor environments.

Rain observations with a vertically looking Micro Rain Radar (MRR)
TL;DR: Simultaneous estimates of rainrate and reflectivity factor with data of a C-band (frequency 6 GHz) weather radar suggest that the MRR may be used to support quantitative rainrate estimates with weather radars.

Radar Observations and Simulation of the Melting Layer of Precipitation
TL;DR: In this article, the melting layer in precipitation is physically modeled and compared with high resolution Doppler radar data, which includes a new formulation of the dielectric properties and can handle all ice particles with densities ranging from pure snow to hail.

Propagation impairment on Ka-band satcom links in tropical and equatorial regions
TL;DR: In this article, a review of the deficiencies and their likely impact on system performance is presented, highlighting difficulties and encouraging realistic expectations and examining the question of whether costly, application-specific measurement programs might now be avoided by mining increasingly sophisticated national meteorological records.
