First International GOCE Workshop
ESA-ESTEC, 23-24 April 2001

Living Planet   

The First International GOCE Workshop was held on April 23-24th, 2001 in ESTEC, Noordwijk, The Netherlands

International GOCE User Workshop

The objective of the First International GOCE user workshop was to provide a forum for presentations and discussions on the development, use and exploitation of GOCE Level 2 (global and regional) geoid products, and of Level 3 (science and application) data products. The workshop also provided current information on the technical and programmatic status of the GOCE project.

ESA's Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission, scheduled for launch in the 2005 time frame, is a geodetic mission exploiting a unique measurement technique to recover precision data on Earth's gravity field. In particular, GOCE will recover high spatial resolution (~ 100 km) gravity field data, and will provide information with which to advance knowledge of the Earth's reference equipotential surface, the geoid.

Preparations are underway in the International scientific community for exploitation of GOCE gravity data along with other geodetic data sources. These include use of the GOCE gravity field or geoid in various scientific applications. Moreover, GOCE data could be compared and/or combined with other gravity data derived from the ongoing German Challenging Minisatellite Payload mission (CHAMP) for geoscience and application or the US-German Gravity Recovery and Climate Experiment (GRACE) mission (planned for launch in 2001). Resulting high-precision geoid data are expected to have an impact in Oceanography, Solid-Earth Physics, Geodesy, Glaciology and Climate-change research.

The goal of the GOCE mission is to deliver a high-precision gravity potential field, and global gridded geoid heights and gravity anomalies to the scientific community. ESA is presently coordinating efforts to produce a validated high-resolution gravity and geoid model. Various groups and consortia throughout Europe have also expressed an interest in development of either level 2 or level 3 products, and in pursuing GOCE-related research. This workshop provides an opportunity to publicise these higher-level data processing plans and to coordinate such activities.
