Prediction of Attenuation by Rain

IEEE Transactions on Communications, 1980
A new model is presented for the prediction of attenuation by rain on either terrestrial or slant earth-to-space propagation paths. The model was developed using geophysical observations of the statistics of point rain rate, of the horizontal structure of rainfall, and of the vertical temperature structure of the atmosphere.

A Stochastic Dynamic Model of Rain Attenuation

IRE Transactions on Communications Systems, 1981
A dynamic mathematical model of rain attenuation has been developed and is presented in this paper. This model permits the expression of analytic relationships between parameters commonly used to describe the properties of interest for communication. The dynamic model is based on the lognormal distribution of rain attenuation and utilizes a memoryless ...

Rain attenuation statistics from rain cell diameters and heights

International Journal of Satellite Communications and Networking, 2001
AbstractThe prediction of satellite link attenuation is generally based on the point rainfall rate for 0.01 per cent of the year. The physical quantity used to determine attenuation is rain rate, whereas the 0.01 per cent point is a more complex parameter, not obviously related to the dynamics of rain structure.

Rain height study to predict satellite link rain attenuation

2020 30th International Conference Radioelektronika (RADIOELEKTRONIKA), 2020
The height of rain and the zero isotherm height serves as an important parameter to define the satellite link length in the rain volume. This enables to estimate the important rain attenuation. We introduce 5 known models of rain height and computed the zero and minus 15°C isotherme heights in Prague.

Rain rate and rain attenuation prediction with experimental rain attenuation efforts in south-western Nigeria

2012 20th Telecommunications Forum (TELFOR), 2012
This paper presents the comparison of existing rain rate models with three years one minute average rain rate obtained using a vertically looking micro rain radar. The improved Moupfouma model showed good agreement with the measured rain rate. Rain attenuation for selected broadcast satellites with varying look angles was also estimated.

Effect of rain structure on rain induced attenuation

Annales des Télécommunications, 1977
The effect of rain structure on rain induced attenuation is examined. The important role of raindrop-size distribution is evident from the comparison between experimental and calculated data. Commonly adopted parameters for calculating specific attenuation versus rainfall intensity are acceptable for system design at 18 GHz but tend to underestimate ...
