Abstract

Abstract: There is a certain correlation between precipitable water vapor PWV and atmospheric pollutant PM_2.5 in the frequent occurrence of haze. In view of this, the correlation between GNSS atmospheric precipitable water and PM_2.5 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 PM_2.5 during the frequent haze episodes in Henan, and the established real-time monitoring model of PM_2.5 verifies that it can be based on atmospheric precipitable water PWV. Real-time monitoring of PM_2.5, and achieved a more satisfactory result, this technology method has a high application value, can provide a new reference for the current PM_2.5 monitoring.

Key words: precipitable water vapor, CORS, PM_2.5 detection, correlation
