Abstract—Effect of sea salt aerosol on short wave spectrum energy is the study of solar reduction and the reduction percentage due to sea salt aerosol. The research measured short wave radiation from the sun by using spectroradiometer, model MS700. The spectroraiometers were installed at two levels: the first level was set at 10 meters height from ground that called “control unit” representing the rays of the sun directly (direct Incoming) and the second level was set at one meter height that called “blank unit” measuring radiation from the sun passed through the blank chamber (Representing a decrease in solar radiation on Chamber / blank) and “laboratory unit” was a chamber with dry sea salt aerosol (Representing a decrease of the radiation from the sun and dried sea salt), then the study would find the percent reduction of solar radiation. The results show that the concentration of sea salt aerosol from 0.48, 0.85, 1.22, 1.59, 1.96 g/m3. Aerosol particles caused the solar radiation reducing rate higher than sea salt aerosol at wavelength 306- 330 nm due to high energy (short wavelength) In addition.wave-length 380-390 nm increase solar radiation f due to the properties of sea salt crystals 570-590 nm and 710-750 nm showed rapidly reduce energy.
