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

Observation of bright-band height data from TRMM-PR for satellite communication in South Africa
TL;DR: In this paper, the effect of rain on a satellite link operating at a frequency above 10 GHz can be estimated using various parameters such as rain rate, drop size distribution, and rain height.

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.

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.
