In this paper, contour maps of rainfall rate and rain attenuation are developed for the first time in Venezuela. It is based on 1-min rain rate statistics obtained from measurements carried out in Venezuela over a 30 years period with a higher integration time. The Rice-Holmberg model, refined Moupfouma-Martin model and Recommendation ITU-R P.837-7 for rain rate estimation were used, while Recommendation ITU-R P.618-13, Ramachandran-Kumar model, Yeo-Lee-Ong model and Rakshit-Adhikari-Maitra model were used for rain attenuation prediction in “Simón Bolívar” satellite links in Venezuela. The results of both types of maps represent a useful tool for preliminary planning of those links in the country, specifically, in Ku and Ka-bands. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49662418004 https://www.redalyc.org/journal/496/49662418004/ https://www.redalyc.org/journal/496/49662418004/html/ https://www.redalyc.org/journal/496/49662418004/49662418004.epub https://www.redalyc.org/journal/496/49662418004/movil 10.15446/dyna.v86n209.73774 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.209 Vol.86 |
