Reporting period: 15 November 2005 - 31 December 2005 The first reporting period of the
GlobColour project has been very active. Several feedbacks have been received
including during the Christmas holiday period, thus allowing to get an
updated version for discussion at the SRR. Rosa Barciela from the National Centre for Ocean Forecasting (UKMO) has also accepted to act as an operational oceanography user on December 17. The first User workshop will be held at LOV (Villefranche) in collocation with Medspiration workshop early December 2006. The System Requirements Review Meeting is planned to be held at UNESCO (Paris) on Jan. 3-4 2006. The GlobColour web site will be publicly open on January 16, 2006. On December 31, 2005, the team is complete except for one position still open at UoP for a two-year Post-doc.  Reporting period: 1 January 2006 - 31 January 2006 January 2006 has been very active,
starting on 3-4 January with the System Requirements Review hosted by
IOCCP at UNESCO (Paris). As planned, the GlobColour
web site has been publicly open on 16 January 2006. Following contact with IOCCG and potential providers (including a DDS PI), the need to define terms for the usage of the in-situ and EO data has been confirmed. Further direct discussions occurred
between ESA and NASA on this subject and are still on-going at the end
of January. A complete set of technical inputs
has been delivered to the development team together with a draft Technical
Specification table of contents on 25 January. Reporting period: 1 February 2006 - 28 February 2006 February 2006 has been focused on
the technical specification. Although no major issues have been
raised so far, the iterations on the requirements have prevented the consortium
from issuing version 1 of the Technical Specification and of the Design
Definition File in February. During this period, the team has selected a candidate for the position open at UoP; two-year Post-doc. Lastly, an abstract has been prepared for the NASA Ocean Color Team Meeting. Reporting period: 1 March 2006 - 31 March 2006 March 2006 has been focused on the technical specification and initial software development and version 1 of the Technical Specification has been delivered. Requirements Baseline and Validation Protocol have been approved early March by ESA. A further revision loop has been performed on the Design Justification File, including dedicated sections addressing a preliminary analysis of the sensor characterisation based on a survey of existing results as well as the up-to-date results from the last MAVT meeting. Although no major issues have been raised so far, the iterations on the Technical Specification - which is the technical reference that is used to build the architectural design of the data processing system - have prevented the consortium from issuing version 1 of the Design Definition File in March. Several products have been prototyped and preliminary intercomparison of diffuse attenuation coefficient derived from MERIS, MODIS and SeaWiFS has been performed. Next period will be dedicated to software development and generation of Diagnostic Data Set products according to technical specification. Characterisation campaigns will be launched according to the rules established in the Validation Protocol. Lastly, several team members will participate to the NASA Ocean Color Team Meeting and GlobColour will be presented. Reporting period: 1 April 2006 - 30 April 2006 The System Requirements Review has been successfully completed in April 2006 with the following set of documents
The Preliminary Design Review is on going; feedback has been received on version 1 of the Technical Specification (TS) and an updated version has been submitted. Version 1 of the Design Definition
File (DDF) has been submitted. Next period will be dedicated to

scientific community, increase the awareness of the
GlobColour service, with main NRT aspects of GlobColour
transferring to the EU GMES Ocean Colour TAC.
Reporting period : 1 January 2009 - 31 March 2009
The first quarter of 2009 has seen the consolidation of the user base, with 304 registered
GlobColour users from 67 different countries and more than 1 terabyte distributed on user
request via the Hermes data server (
http://hermes.acri.fr/). In addition, 34 users have
subscribed the 1km NRT local service with 12697 local products distributed during the
period. Positive user feedback is regularly received.
The
GlobColour poster that was presented at Ocean Optics and addresses the uncertainties
estimates approach taken by GlobColour to supply error estimates at pixel level has
triggered the interest of the ocean colour community, with several feedback received.
The global NRT service delivers every day 19 ocean colour products at global scale,
including Secchi disk depth that is now available in NRT too. A one year demonstration of
primary production has been generated for year 2003.
A GlobColour presentation has been submitted at IGARSS 2009 and accepted.
The period has also been fruitful in exchanges with the MyOcean project, resulting in
GlobColour products now available via the MyOcean catalogue v0
http://www.myocean.eu.org/repository/full_catalogue_v0.pdf

open to the scientific community, increase the awareness of the GlobColour service, with
main NRT aspects of GlobColour transferring to the EU GMES Global Ocean Colour TAC.
Reporting period : 1 April 2009 - 31 July 2009
At the end of this reporting period which marks the end of the GlobColour project, it is worth
recalling ESA's goal in creating GlobColour that was:
Regarding the second goal, a complete one year experiment of assimilation of GlobColour
products has been successfully achieved by the UK MetOffice and a summary of the
promising results are available on the Hermes server
http://hermes.acri.fr/Share/assimil.pdf.
The third goal is fully achieved since the service is continuing although the contract is
ending.
Indeed, in the frame of the EU GMES MyOcean Ocean Colour TAC, and of the national
funded REGICOLOUR project, services continue under the banner of GlobColour:
