GPS time series as proxies for regional climate change
• Trend changes in GPS time series reflect ‘large’ load changes induced by glacier/icecap melt, lake level changes, or drought. • Year-to-year seasonal changes reflect climatic signals. • Western US – GPS-climatic signal is dominated by hydrological changes and correlates with the Palmer Severe Drou...

| Summary: | • Trend changes in GPS time series reflect ‘large’ load changes induced by glacier/icecap melt, lake level changes, or drought. • Year-to-year seasonal changes reflect climatic signals. • Western US – GPS-climatic signal is dominated by hydrological changes and correlates with the Palmer Severe Drought Index (PSDI). • East coast – GPS-climatic signal correlates with the North Atlantic Oscillation (NAO) and possibly is induced by non-tidal ocean loading. • GPS time series can serve as independent proxies for regional-scale climate change. |
