Abstract: 主要研究AERONET(Aerosol Robotic Network)提供的的气溶胶光学厚度(Aerosol Optical Thickness,AOT)与空气污染指数(Air Pollution Index,API)之间的相关性。对北京地区2004年全年AERONET提供的气溶胶光学厚度和环保局监测的API进行了相关性分析,发现二者直接对比相关性较低。考虑到AOT的主要影响因素,从以下三个方面进行了探讨:①将数据分成四个季节,构建二者相关性模型;②将经过气溶胶标高垂直订正的AOT数据与API建立相关模型;③考虑到湿度影响因子的作用,按水汽分段分析AOT与API的相关性,发现相关性明显提高。
