Abstract
Knowledge of the size and chemical composition of aerosols is important to assess their role in several processes occurring in the atmosphere. The aerosol optical thickness is a byproduct of the atmospheric correction, but it is possible to research atmospheric aerosol by those byproducts. In this paper, we first calculated the aerosol optical thickness over other wavelengths using SeaWiFS-derived aerosol optical thickness at 865nm and atmospheric-correction parameters ε(λ,865). Then we classified the aerosol over the ocean into three classes: nuclei mode (r < 0.04μm), accumulation mode (0.04μm < r < 1.0μm) and coarse mode (r > 1.0μm), which are all described by the log-normal distribution. The derived relationship of aerosol optical thickness and number distribution at different wavelengths and Monte-Carlo method are used to obtained the total number of those three classes over the ocean and we analysis their distribution. The reasonable results show that the aerosol optical thickness by SeaWiFS is nice for atmospheric aerosol research.
