| 摘 要： | 利用NASA MODIS气溶胶光学厚度(AOD)产品与南京市区API转换得到的PM10质量浓度进行了相关性分析;发现二者的直接相关程度较低。对气溶胶光学厚度进行垂直和湿度影响订正后,二者的相关系数显著提高。结合风速和气压等气象因子分季节进行多元回归分析,相关系数进一步提高。分析结果表明卫星遥感气溶胶光学厚度可以作为监测PM10污染分布的有效手段。

| Abstract: | This study was based on MODIS aerosol optical depth(AOD) product and PM10 mass concentrations calculated from Air Pollutant Index (API) in Nanjing. The direct correlation between AOD and PM10 mass concentration was found relatively low. The correlation significantly improved after taking aerosol vertical distribution and influence of relative humidity (RH) into consideration. The correlation further improved after taking into account the meteorological factors such as wind speed and atmospheric pressure to conduct seasonal multi-regression analysis. The analysis verified that the MODIS AOD is an effective means for monitoring PM10 mass concentrations. |
