Abstract
Aerosol models are widely used in satellite remote sensing to derived aerosol mode from aerosol optical and microphysical properties. One year of ground-based aerosol remote sensing observations were carried out using sun-sky radiometer measurements in Zhoushan (122.1897E, 29.9944N), Zhejiang Province, Eastern China. At the same time column Aerosol Optical Depth (AOD), Ångström exponent (AE), Single Scattering Albedo (SSA), asymmetry factor (g), complex refractive index and column aerosol volume spectral distribution were retrieved by mature code as well as some procedures, such as radiometer calibration, cloud screening and data selection strategies. Aerosol size parameters were separated as fine effective radius (rvf) and coarse effective radius (rvc) due to the column aerosol size distribution is generally bimodal lognormal distribution. The relationship between these parameters and effective radius was shown and analyzed. It is shown that aerosol in Zhoushan is urban-industrial type dominate, mixed with marine aerosol and mineral dust aerosol. As a result, this study showed a part of aerosol comes from mainland industrial areas by using the backward trajectory model.
