| 摘 要： | 2014年12月29—30日,青岛市发生了一次空气污染过程,利用环境一号卫星CCD遥感影像数据和实测PM_(2.5)浓度数据,分析了该过程前后5 d的实测PM_(2.5)浓度与环境一号卫星CCD遥感影像的DN值之间的相关性,分别按日期和区域建立了反演模型。结果表明,按日期拟合反演模型相关系数为0.02~0.51,按区域拟合反演模型相关系数为0.01~0.80,总体来说,区域拟合结果较好。

| Abstract: | During December 29 to 30th 2014, an air pollution event occurred in Qingdao City. By using HJ-1 CCD data and ground-based measurements, the correlation of ground-based PM2.5 and DN value of HJ-1 CCD during five days pre and post this process was analysed, and the PM2.5 retrieval models were established respectively by days and regions. The result showed that, the correlation coefficient between the retrieved and measured PM2.5 by days was between 0.02 and 0.51 and that by regions was between 0.01 and 0.80.Overall, the result of the model established by days was better. |
