Analyzing the Impact of Climate Factors on GNSS-Derived Displacements by Combining the Extended Helmert Transformation and XGboost Machine Learning Algorithm

Figure 5

Plots showing the three-component displacement time series of the BYSP station with respect to two different scale reference frames: a global reference frame (IGS14) and a local reference frame (PRVI19). The green dots represent the displacements with respect to the PRVI19 reference frame during 2008-2020. The red dots represent the displacements referred to the IGS14 reference frame within the same period of time.
