| Abstract | The objective of this work is to verify the application of models which allow reconstituting monthly averages a day global and diffuse radiations on a horizontal plan. Chosen models were proposed in the literature by various scientists and relative to several sites in the world. This models are a function of main meteorological parameters of which ambient temperature, relative humidity, sunshine duration and about astronomical parameters such as the declension of the sun, the astronomical duration of day, the constant solar, the earth sun distance variation and the monthly average a daily of the extraterrestrial radiation calculated on a horizontal plan on the atmosphere limit. So we confronted these models with values really measured on several Algerian's sites which Bouzareah, as coastal site, Batna on the high trays, Ghardaia and Adrar in the North and in the South of Sahara respectively. As results, we noticed that according to respective climatic characteristics in the considered site, some models underestimate these constituents; the others overestimate them while the others are in good agreement with moderate values of error. So the models retained respectively are Hussain's models and al. and that of Garg and al. for the estimation of the global radiation and the models of Erbs, Klein and Duffie and Liu & Jordan for the reconstruction of the diffuse constituent. Mots cles: Irradiation diffuse - Irradiation globale - Indice de clarte - Duree d'insolation. |
