Abstract

Abstract: 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 PM_2.5 in spring, summer, autumn and winter in Beijing.It has found that the correlation between PWV, ZHD and dust-haze concentration PM_2.5 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.

Key words: GNSS, water vapor, dust-haze concentration, correlation, monitoring and warning
