Abstract In recent years, the Global Navigation Satellite System (GNSS) has witnessed rapid development. However, during the sandstorm season, the precipitable water vapor ( PWV GNSS ) determined from the GNSS data produces large fluctuations due to the influence of particulate matter, which can indirectly reflect the change in particulate matter concentration. To study the variations of PWV GNSS during the sandstorm season, daily data of PWV GNSS , particulate matter ( PM10 ), and precipitation in Wuhai from 2017 to 2021 were used in this study. The principal components of PWV residual ( PWV RPC ) were obtained by using the least-squares linear fitting, singular spectrum analysis, and least-squares spectral analysis on PWV GNSS . The principal components of PM10 ( PM10 PC ) were obtained by using least squares linear fitting and singular spectrum analysis for PM10 . This study performed a correlation analysis of PWV RPC with PM10 PC and precipitation data. The results showed a strong correlation between PWV RPC and PM10 PC , with a correlation coefficient greater than 0.6. However, it was found that the correlation between PWV RPC and precipitation was not significant. This indicates that during the sandstorm season, PM10 affects PWV determined from GNSS data.
