This study utilizes the environmental loading products derived from different data sources provided by GFZ and GGFC, to correct the atmospheric loading, non-tidal ocean loading and hydrological loading of 50 GNSS stations in Beijing and its surrounding areas. The RMS reduction rate of the GNSS coordinate time series after environmental loading corrections is used to evaluate the performance of different products. The results show that the impact of atmospheric loading is more significant than that of hydrological loading, and the impact of non-tidal ocean loading can be ignored. The RMS values of all the GNSS height time series except that of LNJZ station are reduced after the correction of atmospheric loading products provided by GFZ and GGFC, and the average RMS reduction rate is more than 15%, indicating that the impact of atmospheric loading on the vertical motion of GNSS stations in the study area is nonnegligible. The correction effect of different atmospheric loading products provided by GFZ and GGFC are similar, the correction effect of non-tidal ocean loading products derived from MPIOM provided by GFZ is better, and the correction effect of hydrological loading products derived from GLDAS provided by GGFC is better.
