GOCE research in Germany: From sensor analysis to Earth system science

Abstract

GOCE Level 2 research in Germany is focussed on various gravity field estimation approaches, on calibration and validation of GOCE gravity field gradients and gravity field models using terrestrial gravity field observations and marine data. Research on these fields is supported by the federal Geotechnologien research programme. GOCE Level 3 research is focussed in the new priority research programme of the German Research Foundation "Mass Transport and Mass Distribution in the Earth System". The programme (starting in autumnn 2006) aims at an interdisciplinary effort on the study of mass related processes and signals based on data from CHAMP, GRACE, GOCE and satellite altimetry. It includes projects on global and regional ocean circulation, on structure and dynamics of mantle and crust (using GOCE data) as well as GRACE related research on temporal mass variability and mass exchange. From the viewpoint of GOCE users, the integration into Earth system research is particularly attractive. The GOCE project bureau Germany at Technische Universität München is engaged in coordination of these level 2 and level 3 activities. Workshops and round tables have been organized on themes such as GOCE gravity field analysis, inverse problems, on mass transport and mass distribution in the Earth system, and on future perspectives for satellite gravimetry. The paper summarizes the current status and research activities on these fields. Additional information in German language can be found at http://www.goce-projektbuero.de.
