Estimation of insolation over the central Red Sea

الملخص EN

The monthly means of clear sky insolation over the central Red Sea were estimated by Smithsonianís and Lumbís formulae and their annual averages were 287 W.mñ2 and 292 W.mñ2.

With the cor-recting factor of 0.92 and the attenuation by clouds, the annual aver-age was 252 W.mñ2.

The monthly estimated radiations are then com-pared with the recorded radiations from five stations around the latitudinal belt of the central Red Sea.

An 11% average reduction of the estimated radiations agreed well with the recorded radiations.

This reduction has been attributed to the aerosols as the Red Sea lies in a dusty environment.
