Abstract

This article utilized aerosol product of MODIS and aerosol data provided by AERONET which is real-time monitoring data about aerosol in a station to study spatial-temporal changes of aerosol in the Yellow Sea of China in 2006, and adopted some indexes such AOD (Aerosol Optical Depth) and Angstrom index (α and β), and analyzed monthly distribution and annual average of aerosol. The result suggested that AOD had significant negative correlation with Angstrom-α (r=-0.7261), and significant positive correlation with Angstrom-β (r=0.9576), and Angstrom-α had significant negative correlation with Angstrom-β (r=-0.8791). AOD and Angstrom-β came up to the maximum in Spring, then in Summer and Winter, and down to the minimum in Fall in the study area, and Angstrom-α was completely opposite. AOD and Angstrom-β had a upward trend from offshore to deep sea area, and from the north to the south of the Yellow Sea, while Angstrom-α had a downward trend. Analysis of Angstrom-α displayed that the offshore was polluted by small particles from anthropic activities, and the main content of aerosol was large particle of sea salt in the deep sea field. The main type of aerosol was consisted of small particle aerosol emitted from anthropic activities in Summer and Fall, and of sea-salt particle in Spring and Winter in the Yellow Sea. Spatially the diameter of aerosol in the north of the sea was bigger than one in the south. This study obtained the general distribution spatially and temporally in the Yellow Sea of China, and especially the fact that the main content of aerosol in the offshore was small particle from anthropic activities was paid attention to
