| 摘 要： | 通过与地基气溶胶观测数据的对比,确认了MODIS,Sea WiFS气溶胶光学厚度产品用于研究中国海域气溶胶分布和变化特征的有效性.在此基础上,交叉比较了MODIS和Sea WiFS的气溶胶三级产品,发现他们在空间变化趋势上是一致的,在中国海域的气溶胶光学厚度都是随着离岸越远,气溶胶的光学厚度越来越小,在北纬30°-35°有高值区,在靠近大陆的沿岸地带也是气溶胶的光学厚度的高值区.Sea WiFS反演的气溶胶光学厚度整体比MODIS反演的气溶胶光学厚度偏高,两者的年平均气溶胶光学厚度有明显的区别.

| Abstract: | the Aerosol optical depth from MODIS and SeaWiFS over east of China sea are validated with that of AERONET ground-base measurements,the results show the feasibility of the two dataset on the study of aerosols chrematistics over China sea. The inter-comparison of the L3 products between MODIS and SeaWiFS shows great agreement in the space variation of AOD. The AOD decreases with the farther away from the coast and there is of high value in 30N-35N and near coast line. Generally,the value from SeaWiFS is a little larger than that of MODIS by 0.01-0.02,for the annual average. |
