| Abstract | The global and diffuse solar radiation on the horizontal surface at Amman-Jordan during the period from January 2008 to December 2008 is analyzed and presented in this paper. The annual mean of the daily global and diffused solar radiation is about 20.3875MJ/m2 and 4.5 MJ/ m2 respectively. On yearly average basis the percentage frequency of cloudily days (KT<0.30)is quite low, namely 9.5%, whereas that for clear days is quite high (KT>0.70)52.6%the average monthly clearness index varies from 0.757 in January to 0.564 in December while the average monthly diffuse fraction ranges between 0.320 in January and 0.163 in July. The highest fraction of the days radiation was observed in the moderate radiation period(9-11+13-15) and confined between 51% in winter and 37% in summer. |
