摘　　要：介绍了利用GNSS观测数据反演大气可降水量PWV的相关原理,分析了北京地区春、夏、秋、冬时节的可降水量、天顶干延迟ZHD与雾霾浓度PM2.5的相关性,通过分析发现北京地区不同季节的PWV、ZHD与雾霾浓度PM2.5的相关性表现出较大的差异性,冬季的相关性最强,春季和秋季的相关性次之,夏季的相关性最弱。通过试验分析,笔者认为利用GNSS反演获得的PWV、ZHD等气象数据在一定程度上可用于雾霾灾害天气的监测和预警。This paper introduces the principle of using GNSS observation data to retrieve atmospheric precipitable water,and analyzes the correlation between PWV,ZHD and dust-haze concentration PM2.5 in spring,summer,autumn and winter in Beijing.It has found that the correlation between PWV,ZHD and dust-haze concentration PM2.5 in different seasons in Beijing shows great difference,and the correlation is the strongest in winter,followed by spring and autumn,and the weakest in summer.Through experimental analysis,this paper proposes that the PWV,ZHD and other meteorological data obtained by GNSS can be used for monitoring and early warning of dust-haze disastrous weather to some extent.
