[G02-P-14] GOCE and beyond: Status and activities

Rune Floberghagen, Roger Haagmans, Michael Kern (European Space Agency)

This presentation provides an overview of the current status of activities in ESA related to the Gravity field and steady-state Ocean Circulation Explorer (GOCE) mission which was ESA's first Earth Explorer in orbit between 17 March 2009 and 11 November 2013. GOCE determined geoid heights with centimetre-level accuracy and spatial variations in the static gravity field to one part per million (ppm), in both cases with a (half-wavelength) spatial resolution of 100 km on Earth's surface. The geoid, gravity and gravity gradients of GOCE have been used for many scientific and practical applications. These related to for example to oceanography, solid Earth geophysics, aeronomy, height unification and GNSS levelling. Also more recently studies on time variations of gravity signals and ice mass balance were performed and global modelling efforts like 3D Earth were initiated. Recently, the latest, most up to date GOCE processing that led to the release 5 models has been critically reviewed and ideas for the future activities emerged. These will also be presented.
