Abstract
This study evaluates MODIS C6.1 3km aerosol optical thickness (AOD) product with different solutions and different quality control strategies against ground-based observations over Yuandao in the North Yellow Sea. AOD data obtained from datasets “Effective_Optical_Depth_Best_Ocean”, “Effective_Optical_Depth_Average_Ocean”, “Optical_Depth_Land_And_Ocean” and “Image_Optical_Depth_Land_And_Ocean” are evaluated separately. Results showed that they are all well correlated with ground based observations, and AOD data from “Optical_Depth_Land_And_Ocean” with “average solution” and QAC<0 perform best. Seasonal variation are obvious and similar for the 4 datasets, AOD for autumn show the best performance while spring show the worst. Combined effect of dust aerosol, urban pollution and biomass burning aerosol may be the reason for the lower precision in spring.
