台湾海峡及周边海区MODIS气溶胶光学厚度有效性验证
Validation of MODIS aerosol optical thickness in the Taiwan Strait and its circumjacent sea area

摘要: 大气气溶胶通常是指悬浮在大气中直径小于10μm的液态或固态的微小粒子.对流层气溶胶是陆地-大气-海洋系统的重要组成部分.它通过直接或间接辐射强迫强烈地影响着地-气系统的辐射收支平衡,进而影响全球环境和气候,是气候变化研究的一个重要因子.气溶胶光学厚度是气溶胶最重要的参数之一,是表征大气浑浊度的重要物理量,也是确定气溶胶气候效应的一个关键因子和大气模型的一个重要参量[1].探测气溶胶光学厚度可以采用陆基探测方法,如太阳辐射计、天空辐射计、日射强度计等,也可以采用卫星遥感观测的方法.
