基于MODIS数据的江浙沪地区大气气溶胶光学厚度研究

摘要

大气气溶胶是影响环境和气候的重要因子，其光学厚度是表征大气浑浊度的一个重要因素。该文利用2011-2012年MODIS Level 2（MOD 04）气溶胶产品分析了江浙沪地区气溶胶光学厚度的分布和季节变化特点，结果表明江浙沪地区气溶胶光学厚度峰值出现在春夏两季，并且峰值有由春季向夏季转移的趋势。%The influence of atmospheric aerosols is an important factor in the environment and climate,atmo-spheric characterization of atmospheric aerosol optical thickness is an important factor in turbidity. In this paper,2011-2012 years MODIS Level 2(MOD 04)analyzed the aerosol products of aerosol optical thickness Intra Regional distribution and characteristics of seasonal variation was found that the aerosol optical depth of Changjiang peak in spring and summer,and from spring to summer peak with the transfer of the trend.
