Remarks

・φ:Latitude.North(+),Siuth(-).
・δ:Declination of Sun.North(+),Siuth(-).
・ωs:Solar Hour Angle at Sunset.
・H0(J/m^2/day , Wh/m^2/day):Monthly Average Extraterrestrial Daily Solar Radiation on a Horizontal Surface.
・LaTex: \\\textup{Daily Extraterrestrial Radiation}(H_{0})\\\\=\frac{86,400G_{sc}}{\pi }(1+0.033\cos(2\pi \frac{n}{365}))\\\times (\cos\phi \cos\delta \sin\omega _{s}+\omega _{s}\sin\phi \sin\delta )
