✦ Synopsis

Correlations for calculation of the diffuse component of the daily and monthly average solar irradiation in terms of the clearness index are obtained from available data at both rural and urban locations in Greece. These correlations are mostly of first and occasionally second order in the clearness index and strongly reflect the higher levels of diffuse radiation present in Greece. No evidence of significant seasonal variation has been found, while air pollution in the urban areas is seen to play a small role only in the summer months and at high clearness index values.
