根据连续2天卫星遥感气溶胶光学厚度（AOD,Aerosol Optical Depth）实例,2011年4月26日AOD的高值区位于成都市区附近,27日迁移至德阳中部;27日绵阳城区及其附近的AOD次高值区是由当地累积、扩散而成;高值区的迁移与大气流场和地形特征密切相关。气溶胶颗粒物不属于四川盆地之外输入;较之以往更详细地展示了当地AOD的空间分布状况。
根據連續2天衛星遙感氣溶膠光學厚度（AOD,Aerosol Optical Depth）實例,2011年4月26日AOD的高值區位于成都市區附近,27日遷移至德暘中部;27日綿暘城區及其附近的AOD次高值區是由噹地纍積、擴散而成;高值區的遷移與大氣流場和地形特徵密切相關。氣溶膠顆粒物不屬于四川盆地之外輸入;較之以往更詳細地展示瞭噹地AOD的空間分佈狀況。

According to the data of aerosol optical depth （AOD） observed by satellite remote sensing for two consecutive days, the high AOD area located near Chengdu on April 26th, 2011 and then moved to the center of Deyang the next day; the secondary high AOD area in urban area of Mianyang and its vicinity formed by local accumulation and diffusion on April 27th ; the migration of high AOD areas were closely related to the atmospheric circulations and topography. The aerosol particles did not input from outside of Sichuan. The spatial distribution of local AOD was showed more detailed than before.
