GlobCurrent User Meeting

IFREMER and the European Space Agency (ESA) have sponsored an ocean current data user workshopwhich took place at Ifremer (Brest, France), on 7th to 9th March 2012.

The purpose of this User Consultation Meeting (UCM) was to bring users and experts in the field of EO (calibration, validation, data merging, algorithm development) and service delivery together to present their detailed requirements for ocean surface current products and services. Conclusions and stated user requirements from this meeting will be used to define the scope and develop guidelines for a potential Data User Element (DUE) project "GlobCurrent" competitively funded by ESA. GlobCurrent will demonstrate the feasibility of a unified service for ocean surface currents linked to external user applications.

GlobCurrent User Consultation Meeting : Observing surface currents from space Thanks to satellite and in-situ observations, combined with high resolution numerical ocean models, the last decade has seen advances in the knowledge of the global ocean surface dynamics, filled with a large number of various mesoscale (~100 km) and sub-mesoscale (<~10 km) meandering surface currents and eddies. However, the challenge is to accurately quantify the surface current associated with these…
