SPICE: Environmental space geodesy: detection of changes in glacier mass from time-variable gravity
The primary objective of SPICE is to precisely assess contemporary ice-mass variations of glacier systems (Alps, Alaska, Himalaya, Iceland, Patagonia, etc.) from measurements provided by space gravimetry. Space gravimetry – as realized by the Gravity Recovery and Climate Experiment (GRACE) satellite mission and by the Gravity field and steady-state Ocean Circulation Explorer (GOCE) project – is the only remote sensing technique that allows the direct inference of surface mass changes; access to this information is provided via the temporal variations of the Earth’s gravity field. This project aims to further push the limits of surface mass-variation detection from space, targeting to substantially complement existing glacier change assessments. The outcome of the research will stimulate progress in environmental science and climatology. To successfully accomplish the project tasks, SPICE is based on an interdisciplinary cooperation, involving the (space) geodetic, glaciological und hydrological communities.
