Understanding the Common-Mode Error in Array GPS Displacement Fields: Insights from Taiwan’s Atmospheric Mass Loading
In our study, we explored the common-mode error (CME) in GPS displacement fields across Taiwan, uncovering its significant correlation with atmospheric mass loading (AML). By analyzing 10 years of GPS data from 47 stations, we found that up to 90% of CME variations in the vertical component can be attributed to AML. These findings enhance our understanding of systematic errors in GPS data and offer pathways to improving the precision of geophysical measurements.
