Timeseries (1 hour) of the local sea level changes from GPS
Real-Time Sea Level Monitoring
IGS Tide Gauges
Provide highly accurate long-term time series for the vertical land motion at tide gauges for sea level studies

The Concept
• Stepwise Realization: (1) Direct action(2) Longterm Support
• Modular ConceptCompatible with other systemsExpansion to other disasters (Volcanoes, land slides, meteorological hazards,....)
• Decentralized and open System (National/local Early-Warning-Centres)
• Transferable to other regions
• Recent technological developments
• Capacity Building
