What is the daily extraterrestrial radiation incident on a horizontal surface \( \boldsymbol{H}_{o} \) for Dhahran \( (\phi= \) \( 26.3^{\circ} \mathrm{N} \) and \( \left.L=50.11^{\circ} \mathrm{E}\right) ? \) The daily extraterrestrial radiation incident on a horizontal surface \( \boldsymbol{H}_{o} \) is given by Eq. 1.10.3. \[ H_{o}=\frac{24 \times 3600}{\pi} G_{o n}\left(\cos \phi \cos \delta \sin \omega_{s}+\frac{\pi \omega_{s}}{180} \sin \phi \sin \delta\right) \quad \text { in } \mathrm{MJ} / \mathrm{m}^{2} \] Here \( \boldsymbol{G}_{o} \) is the extraterrestrial radiation normal to a plane surface. \( \boldsymbol{G}_{\boldsymbol{o}} \) on the \( \boldsymbol{n}^{\text {th }} \) day of year is given by Eq. 1.4.1a, as \[ G_{o n}=G_{s c}\left[1+0.033 \cos \left(\frac{360 n}{365}\right)\right] \text { in } \mathrm{J} / \mathrm{m}^{2} \] and where and the sunset hour angle \( \omega_{s} \) is given by Eq. 1.6.10. \[ \omega_{s}=\cos ^{-1}(-\tan \phi \tan \delta) \] The solar constant \( G_{s c}=1367 \mathrm{~W} / \mathrm{m}^{2} \) Other equations: \[ \begin{array}{l} \delta(\mathrm{deg})= 23.45 \sin \left(360 \frac{284+n}{365}\right) \\ B=(n-1)\left(\frac{360}{365}\right)(\mathrm{deg}) \\ E(\text { mins })= 229.2(0.000075+0.001868 \cos B-0.032077 \sin B \\ -0.014615 \cos 2 B-0.04089 \sin 2 B) \end{array} \] where \( B \) is in radians Solar time \( = \) Standard time \( +4\left(L_{s t}-L_{\mathrm{loc}}\right)+E \)
