Effect of atmosphere factors on solar energy-for Iraq marshes

الملخص EN

In this paper, the nature and the magnitude of effect, which caused by atmospheric constituents (Dry air molecular, water vapor, aerosols) on the transmission of solar radiation for Iraq Marshes (Al-Nasiryah Marshes (31° 05 latitude and 47° 17 longitude)), were studied.

It's found that more less solar radiation transmittance occurred by aerosols particles, where its reduces to less than 50 % at high zenith angles (> 60°).

Moreover, the study included the effect of each, the perceptible water vapor and visibility on the intensity of direct radiation as a function to zenith angle in Al-Nasiryah Marshes.

It's found that each of two factors have a clear effect on the direct radiation intensity, but visibility considered as most effected factor on the direct radiation intensity.
