摘要(Abstract)：

基于水汽与GNSS ZTD之间的高相关性,该文利用2015年12月至2016年5月中国大陆环境监测网络(CMONOC)的GNSS数据,借助小波变换方法开展GNSS ZTD与GNSS站点所在城市的PM2.5浓度观测的相关性研究。采用小波变换方法对ZTD与PM2.5进行相同的分解与重构,并对分解重构后的ZTD与PM2.5进行相关性分析。实验表明:基于小波变换方法分解重构的GNSS ZTD与PM2.5浓度的相关性明显高于GNSS ZTD与PM2.5浓度实测值的相关性,在中国华北、华中、西北及东北地区GNSS ZTD与PM2.5浓度的相关性呈显著正相关特性,中国西南以及沿海地区,由于降水及其他因素的干扰,GNSS ZTD与PM2.5浓度的相关性不显著。
