In this work microphysical properties of Maritime Polluted aerosols wereextracted from Optical Properties of Aerosols and Clouds (OPAC) after varying the concentrations of water soluble at five different levels. The analytical expressions for the changes in the equilibrium relative humidity (RH), effective radii, effective hygroscopic growth, their magnitudes and fractional changes on the  effects of surface tension (the Kelvin effect) on the ambient aerosols were numerically  analyzed. The expressions were applied to two - one parameter models. It was  discovered that the increase in water soluble concentration caused decreased in the Kelvin effects which implies decrease in surface tension. The numerical analysis of the data showed that to the lowest order error.   Increase in the overestimation of the effective hygroscopic growth and decrease in the overestimation of the effective radii. On  the two models applied, we discovered that the fractional changes in hygroscopic growth increase in overestimation while there is decrease in  overestimation of fractional changes in effective radii. Finally, decrease in the underestimation of the fractional  changes in the equilibrium pressure it was discovered.

Keywords: Kelvin effect, effective radius, effective hygroscopic growth, water soluble, ambient Relative Humidity, overestimation.
