In this study, a volume based hygroscopicity (kv) model was applied to the data obtained from Optical Properties of Aerosol and Clouds (OPAC), the properties obtained were the radii of arctic, continental clean, continental polluted, maritime clean, maritime polluted, Sahara and urban at eight relative humidity of 0%, 50%, 70%, 80%, 90%, 95%, 98%, and 99%. The Kelvin radii (A) and bulk hygroscopicity (B) were determined using regression analysis, the result shows that B is more dominant than A for maritime clean and maritime polluted, also discovered that maritime clean and maritime polluted has higher value of kv while Saharan has lowest. We also discovered that R2 is greater than 90%, p-value and significance are less than 0.05, therefore the parameter kv is good for atmospheric modeling.
