| 摘 要： | 针对MODIS监测的2006年3月我国新疆区域发生的一次沙尘活动,基于卫星红外窗区3通道(8.5、11和12 μm)方法,自动识别并同步物理反演了沙尘大气的光学厚度、粒子有效半径和垂直气柱沙尘总量,同时利用后向轨迹方法模拟计算的4种高度的气团轨迹对此次反演试验结果的合理性进行了分析和验证,结果表明两者相当一致.

| Abstract: | Based on the three thermal infrared window channels of satellite,a dust event in the Xinjiang Uygur Autonomous Region in March 2006 was investigated.The spatial extent of the dust layer was identified and the optical thickness,particle effective radius and the integral column density of dust layer were retrieved synchronously.A backward trajectory model was used to derive the trajectories of air mass at four different altitudes. The analysis shows that the retrieved results keep the very good relationship with the trajectories of air mass. |

| Keywords: | dust event satellite quantitative remote sensing backward trajectory analysis |
