摘要
利用2009年1 12月兰州地区的MODIS气溶胶光学厚度产品与全球自动观测网(AERONET)SACOL站(104.08 E,35.57 N)数据进行对比分析,相关系数达到0.82,线性拟合的斜率为1.13,截距为0.07,表明MODIS AOD能反映兰州地区气溶胶分布的信息.利用MODIS AOD产品与兰州市空气污染指数做相关分析,二者的相关程度较低.在进行湿度影响因子、气溶胶标高订正后,二者相关性有了较为显著的提高,说明MODIS AOD产品可应用于监测兰州地区大气污染情况.
Using the MODIS products, the aerosol optical depth (AOD) over the Lanzhou area from January to December in 2009 was compared with the ground based observation of AOD at SACOL site(104.08?E, 35.57?N), which is one of the AERONET sites. The results showed that the correlation coefficient was 0.82, the slope of linear fit was 1.13 and the intercept was 0.07. The MODIS AOD could reflect the distribution of aerosol in Lanzhou area. The correlation coefficient between MODIS aerosol optical depth and air pollution index in this area was small. After correcting the humidity factor and aerosol scale height, the correlation coefficient was greater than before. The conclusion is that MODIS AOD products can be applied to monitoring atmospheric pollution in Lanzhou area.
