GlobCurrent User Consultation
A User Consultation Meeting (UCM) was held at Ifremer, France the week of 5 to 9 March 2012 to discuss a potential ESA DUE project dedicated to Ocean Currents.
The objective of the UCM was to evaluate requirements from invited scientific, institutional and operational users communities for high resolution oceanic currents from satellite data.
During the meeting scientists presented the state of the art algorithms to derive surface current from Altimetry, thermal and ocean colour optical signatures and using doppler radar wind or salinity signatures.
The UCM allowed the Agency to evaluate work necessary to improve the existing algorithms, prototype and implement them into demonstration products leading to demonstration services. For example, new synergetic interpretation of upper layer dynamics from 2D expression of surface features in satellite images were discussed.
A preliminary Draft of the User Requirement Document (URD) was presented and developed at the meeting based on user requirements collected and the overall outcomes of the UCM. The URD will form the basis for a further invitation to tender that the Agency intends to issue within EOEP-4 programmatic framework in 2013.
