Development of Cloud Attenuation Model for Satellite Network Links Performance Improvement | Chapter 5 | Advances and Challenges in Science and Technology Vol. 8

 This paper specifies a review of cloud attenuation displaying, using as a case study, a usual research effort accomplished to construct a cloud debilitation model for tropical Ota (6.7oN, 3.23oE), southwest Nigeria. Improvement of the satellite duties availability in all locality is fundamental. All local surroundings areas must build useful important models, such as the cloud debilitation model, which maybe used to determine local link margins for subsidiary network services specifically locations and symbolize correlative resources to applications on worldwide satellites. Effects of suspended moisture (SWD) and suspended icicle crystals (SIC), which constitute clouds, are a significant concern in the design and favorable operation of subsidiary communication systems at recurrences above 3GHz, because the hydrometeors considerably reduce the aids availability as repetitiveness increases. For the purpose of simulating cloud attenuation at a station, the climatic beginning and boundary environments are taken into report as well as the cloud's numerical likenesses to derive the cloud's parametric arrangement equation. The mathematical representations are based on climatological and radiometric dossier that have been assembled through well-designed experiments, at which point cloud parameters are measured utilizing radiance changes traced by satellites and visually noticed surface stations on land and ships in the ocean.  The continuous research project started accompanying an examination of eight basic cloud models at the station, through investigation of the radiosonde and cloud cover data. Then, the study of range analyzer’s dossier on signal attenuation that has existed gathered over a three-year ending is examined. The station dossier from the beacon broadcast experiment to and from the Astra satellite at 28.2oE were then resolved and modelled. This requires comparing the accruing attenuation distribution curves of the range analyzer dossier and those of the station's existing cloud models accompanying the cumulative attenuation classification curves of output dossier generated by each run meeting of the station simulation equation program. The accepted representation of the station cloud debilitation model is given, in addition to further modelling development and future work.   A alone global subsidiary based important model is desirable, where transposable algorithm hopeful used to integrate the differing climatic area models.
