CURRENT AND FUTURE GEODETIC SATELLITE MISSIONS FOR GLOBAL CHANGE MONITORING

摘要

Global change deals with large- and small-scale processes that modify the Earth’s atmosphere, land and ocean. Using innovative geodetic space-borne sensor systems, dedicated gravity field and altimeter satellites monitor these processes over a range of spatial and temporal scales. The integrated analysis of these geometric and gravimetric Earth observation data shall improve the knowledge of system processes of the changing Earth. We here report on valuable contributions from satellite altimetry and satellite gravimetry to Earth system science in general and to hydrology in particular.
