One of the GET’s strengths is its ability to integrate various means of Earth observation. The GET uses a combination of in situ and space-based observations for its research, for example on geology, continental hydrology, the gravity field, or the internal structure of the Earth. Varied methods (watershed monitoring, methods specific to geodesy, analysis of seismic signals) are applied on various space and time scales. In the context of hydrological and geochemical monitoring of watersheds, they cover a wide range of climatic zones (from the arctic to the humid equatorial zone).
