摘要: Abstract The purpose of this study is to establish some correlations on direct normal and global horizontal irradiation for a mediterranean site. have been developed monthly mean values, daily hourly values data. We used linear or polynomial regressions between energetical ratio sunshine duration. For the means I M fits very well duration while, we express h o,h as function H . In all cases, these are, site, in good accordance with experimental Nevertheless, other locations has be developed.
