Abstract Environmental loading effects have spatial differences, in order to provide the basis for subsequent loading data selection to correct reference station coordinate time series. In this paper, we calculate 4 different kinds of environmental loadings (atmosphere pressure, non-tidal ocean, snow pressure and soil moisture displacement time series) that are related to 417 global IGS stations. Referring to the analysis of these data, this article discusses the relationship between the same kind of load displacement of global IGS stations and geographical position. The result shows that the effect of atmospheric pressure on the GPS time series displacement is maximum; the displacement of U direction can reach 20 mm. The effect of snow loading on the GPS time series displacement is minimal. Effects of four environmental loadings on GPS time series in elevation direction can reach the centimeter level. Furthermore, non-tidal ocean and atmospheric loading shows significant regional characteristics.
