摘要
The results of atmospheric effect characterization on the town of Ouagadougou in Burkina Faso are presented and the link with the availability of the direct component of solar radiation is discussed.Experimental meteorological data are treated to set a system of constant references which are used to extrapolate the likely atmospheric effect given by the other experimental meteorological data from 1976 to 2006.As results the periods of strong monthly attenuation of the solar potential are pointed out.
