摘要
在雾霾频发的冬季大气可降水量PWV与大气污染物PM_(2.5)之间存在一定的关联关系,本文通过对河南地区CORS网的GNSS大气可降水量与PM_(2.5)之间的相关性进行分析并建立了实时监测模型。试验研究发现:河南地区冬季雾霾频发期大气可降水量PWV与PM_(2.5)之间存在着较强的正相关关系,通过建立的PM_(2.5)实时监测模型验证了可以依据大气可降水量PWV对PM_(2.5)进行实时监测,并取得了较为理想的结果,可以为当前进行PM_(2.5)监测提供一种新的参考。
There is a certain correlation between precipitable water vapor PWV and atmospheric pollutant PM2.5 in the frequent occurrence of haze. In view of this,the correlation between GNSS atmospheric precipitable water and PM2.5 in Henan area CORS was analyzed and a real-time monitoring model was established. The experimental study found that there is a strong positive correlation between the atmospheric precipitable water vapor PWV and PM2.5 during the frequent haze episodes in Henan,and the established realtime monitoring model of PM2.5verifies that it can be based on atmospheric precipitable water PWV. Real-time monitoring of PM2.5,and achieved a more satisfactory result,this technology method has a high application value,can provide a new reference for the current PM2.5monitoring.
