基于小波相干的雾霾与GNSS对流层延迟相关性分析
|
Abstract:
为了进一步揭示雾霾与对流层延迟相关性的细部特征，基于小波相干算法构建雾霾与天顶对流层延迟（zenith tropospheric delay，ZTD）相关性分析的新方法，有效地分析了雾霾与ZTD相关性的时频空间分布特征及成因。首先，通过分析IGS（internet GNSS service）北京站2014-2017年每个月的ZTD与量化评定雾霾的空气质量指数（air quality index，AQI）的相关系数，发现两者在月尺度上相关系数绝对值大于0.4的比率占29.17%，宏观上显示了两者具有相关性。其次，采用小波相干的方法分析了北京2014-2017年期间年度ZTD与AQI的相关性，发现ZTD与AQI在一定的时频域上具有很强的相关性，并且通过了95%置信度检验。最后，由北京、长春部分时域的ZTD与AQI相关性分析可知，北京3月份ZTD与AQI总体上呈现正相关，并且AQI与温度、气压、湿度和风速具有较好的相关性；在研究时域内秸秆燃烧加剧了北京、长春的雾霾，进而影响对流层延迟
