Measurement of Inland Surface Water from Multi-mission Satellite Radar Altimetry: Sustained Global Monitoring for Climate Change

Multi-mission satellite radar altimetry makes a unique contribution to the monitoring of global inland surface water; existing datasets already allow derivation of decadal time-series over hundreds of targets worldwide. These data are utilised both for climate change research, to inform water resource management, and, in synergy with GRACE data, to examine time-varying gravity signatures from land surfaces and (potentially) measure sub-surface hydrological flow.
