چکیده

The solar radiation reaching the ground level on horizontal surfaces is of paramount importance in many applications, from climate to health (ESRA, 2000), and of course for the production of energy: heat, electricity. This communication deals with the amount of energy received during a day on a surface of 1 m2 located at ground surface and integrated over the whole spectrum of the solar radiation. This density of energy is called daily solar irradiation.

Assessing surface solar irradiance in Northern Africa desert climate and its long-term variations from Meteosat images

Two databases of solar surface irradiance (SSI) derived from satellites are compared to ground measurements for Algeria, Egypt, Libya and Tunisia. It is found that it is possible to accurately derive the SSI from geostationary meteorological satellites, even with a coarse spatial resolution. The two databases HelioClim-1 and SSE exhibit similar and good performances. The bias is lower for SSE t...

Validation of the Surface Downwelling Solar Irradiance Estimates of the HelioClim-3 Database in Egypt

HelioClim-3 (HC3) is a database providing time series of the surface downwelling solar irradiance that are computed from images of the Meteosat satellites. This paper presents the validation results of the hourly global horizontal irradiance (GHI) and direct normal irradiance (DNI), i.e., beam irradiance at normal incidence, of versions four and five of HC3 at seven Egyptian sites. The validati...
