摘要:
以广东省2010-2019年中分辨率成像光谱仪(MODIS)气溶胶产品为数据源,对广东省近10 a的气溶胶光学厚度(AOD)进行时空演变趋势探索和空间异质性分析.通过历史空气质量监测数据,筛选出东莞市典型气溶胶粒子污染事件,并对其进行3个高度上的大气污染物72 h后向轨迹分析.结果表明:在时间上,近10 a广东省气溶胶变化总体上呈现下降和不变的趋势;而在空间上,主要呈现“北低南高”的分布特征,自相关性显著.后向轨迹表明,广东省所受到的大气污染源自不同的高度层,受到台风和季风的影响,以及受到海洋和陆地气溶胶共同作用.
Abstract:
The 2010-2019 moderate-resolution imaging spectroradiometer(MODIS)aerosol products of Guangdong Province were used to explore the temporal and spatial evolution trend and spatial heterogeneity analysis of the aerosol optical depth(AOD)of Guangdong Province in the past 10 years. Based on historical air quality monitoring data, typical aerosol particle pollution events in Dongguan City were screened out, and the 72 hours backward trajectory analysis of atmospheric pollutants at 3 altitudes was performed. The results showed that: in the past 10 years, the aerosol changes in Guangdong Province showed a downward and unchanged trend in general. In terms of space, it mainly presented the distribution characteristics of "low north and high south", with significant autocorrelation. The backward trajectory showed that the air pollution suffered by Guangdong Province comes from different altitudes, which is affected by typhoons and monsoons, and by the combined effects of ocean and land aerosols.
