GGOS monitors global changes through geodesy
The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) provides the essential framework for accurate measurements and consistent modelling and interpretation of Earth system processes and interactions, including global change, Earth deformation, and mass exchange between and within the geosphere, biosphere, cryosphere, hydrosphere and atmosphere.
