| 摘 要： | 利用MODIS资料,对中国东南部地区及近海海域实现多通道大气气溶胶光学厚度(AOD)反演;利用地面连续波段的太阳辐射计数据对MODIS资料的反演结果进行校验,结果表明,反演结果的置信度较高;利用经过校验的结果对该地区的AOD分布特征进行了研究. 结果表明:AOD大值区主要集中在海拔低的东南沿海及经济发达地区,而地形比较复杂的山地丘陵地区的值较小;海洋上空的AOD反演由于受到了近海混浊水体和离水辐射的影响,反演结果偏高,但还没有发现能准确反映研究地区特征的输入参量和合适的算法,以提高近海海域AOD的反演精度.

| Abstract: | The multichannel retrieval of atmospheric aerosol optical depth (AOD)in southeast China and along the coastland was realized using MODIS data. Theretrieval result of MODIS data was validated using continuous data from a sun photometer. The results fit very well and have high correlations, which prove that a reasonable inversion optical thickness has been obtained. The variation and distribution characteristics of AOD over southeast China and the East China Sea were studied, with major results as follows:the high AOD cores are in the developed economic areas with low height above sea level, whereas the situation is opposite in the complicated geography mountainous regions. There is a larger retrieval value over the ocean due to the impact of the coastal turbid seawater and water-emitted radiation, and as a result of lacking the imputing parameters in the area, there is not yet suitable arithmetic to improve the AOD retrieval quality. |
