Linking the Global Geodetic Observing System (GGOS) to the Integrated Global Observing Strategy Partnership

When setting up GGOS as a project, the IAG Exec-utive Committee asked the GGOS Steering Commit-tee to establish a relationship with IGOS-P. IGOS-P addresses a number of problems and components of Earth observing systems in the frame of specific Themes. The IGOS-P Theme process will also be an important mechanism for the development of the com-ponents of the Global Earth Observation System of Systems (GEOSS). Many of the burning questions related to the wa-ter cycle, the climate, global change, and geohazards cannot be solved without sufficient knowledge of mass transports throughout the Earth system and the associ-ated dynamics. All these processes affect the three fun
