结合船基的太阳光度计观测资料和空基卫星遥感的MODIS气溶胶光学厚度资料,研究了我国东部海域气溶胶光学厚度与沙尘天气的关系。通过对不同天气条件下500 nm气溶胶光学厚度的分析,得出晴天(背景天气)、有云和浮尘以及只有浮尘时的平均值分别约为0.2、0.6和1.3以上;将MODIS的气溶胶光学厚度与船基观测资料进行对比之后发现,两者随时间的变化趋势非常一致,但前者在数值上明显偏高;利用订正后的MODIS资料,分析了2006年春季我国东部海域气溶胶光学厚度的时空分布特征,并与我国北方发生的沙尘天气进行了对比,发现两者之间关系密切。

Combining the ship-based observational data by sunphotometer with space-based MODIS/AOD data by satellite, the relationship between AOD and dusty weather over Eastern China seas is studied in this paper. By investigation of 500nm AOD in different weather conditions, it is discovered that the mean AOD during clear day (background condition), cloudy and dusty condition, and only dusty weather are about 0.2, 0.6 and more than 1.3 respectively. By comparing the MODIS/AOD and ship-based observational data, it can be concluded that the variation of them with time are very consistent with each other, while the former is obviously larger than the latter magnitude. Using the revised MODIS/AOD data, the temporal and spatial distribution characteristics of AOD over Eastern China seas are analyzed. By comparing these characteristics with dusty weather occurring in north China, it is found that the relationship of them is very close.
