摘要
大气气溶胶是影响气候变化的重要因子之一,利用遥感手段不仅可以获得气溶胶的分布信息,也可以得到相关的气溶胶光学特性参数。气溶胶卫星遥感反演已经成为国际热点,但是反演方法基本上都是采取建立查找表的方法。针对该方法进行了一定的误差分析,将插值结果与真实结果进行比较,得到了一些初步结果。
Atmospheric aerosol is one of the important factors on climate change.Remote sensing retrieval method not only can obtain the distribution of aerosol,but it also can get relevant aerosol optical characteristic parameters.Retrieval of AOD using remote sensing has become the international hotspot.The common method of retrieval of AOD is to establish look-up table using atmospheric radiative transfer modeling.Aiming at the method,certain error analysis was made and the interpolation results of AOD were compared with real AOD.And some preliminary results were obtained.
