【摘要】 将云看作由众多冰水同心球粒子所构成,建立冰水同心球模型。模拟冰水混合云,计算可见光(0.66μm)和近红外波段(1.64μm和2.14μm)的反射函数和光学厚度,建立查找表。选取MODIS卫星数据中1通道、6通道和7通道数据,用最小方差拟合法反演光学厚度、有效粒子半径,和MOD06数据中的光厚度和有效粒子半径对比结果较一致,实验结果表明提出的冰水混合云的反演方法具有合理性。更多还原

【Abstract】 In this paper,cloud is considered as consisting a large amount of ice hybrid concentric spheres,and the ice hybrid concentric sphere model is established.Ice hybrid cloud is simulated,and the reflex function and optical thickness of the visible band(0.66μm)and near-infrared band(1.64μm and 2.14μm)are calculated.A lookup table is established.The data channel 1,6and 7of satellite MODIS are chosen.The minimum variance fitting to invert optical-thickness,effective particle radius is used,which matches successfully with MODIS data.The experimental results show the rationality of ice hybrid cloud model.更多还原
