  2. CCI ECV Validation • Two level of Activities: • Validation and Error Characterisation Internal to each CCI Project, • ECV Data Product Assessment through the Climate Modellers User Group (CMUG).

  3. Requirements • Each CCI project team (the contractor): • Within Europe: shall take full advantage of existing results, on-going projects, and future funding opportunities from national research programmes, from EUMETSAT and from the EC 7th Framework Programme, when planning, implementing and reviewing the progress of their CCI project. • On the international scene: shall coordinate activities with non-European teams, and seek independent scientific review of methods and validation of results, under the auspices of the authoritative international scientific bod(ies), most appropriate for each ECV.

  4. Cardinal Requirement • Each CCI project (the contractor) shall meet the following “Cardinal Requirements”: • Develop and validatealgorithms to meet GCOS ECV requirements for (consistent, stable, error-characterized) global satellite data products from multisensor data archives.

  5. Task 2

  6. Comprehensive analysis of existing methods through consultation process 11 datasets evaluated  state-of-the art description ofdata and error characterization in use in the community - “The Real World” chapter of ATBD. New classifications of errors introduced removing inconsistencies in existing terminology - “Theory (ideal world)” chapter of ATBD. Recipes to combine the ideal and real worlds are given Ozone_cci: ”reviewmethods” Harmonized data and error characterization

  10. Some examples

  11. Aerosol Optical Depth

  12. Ocean Colour CCI Products Daily Error specification (RMSE and bias) based on comparison with match-up in situ data & extrapolation to global ocean Weekly Improved spatial coverage, even at weekly scale Monthly Annual Error-characterisation

  13. GCOS Requirements First of its kind, based on user feedback, according to a method that uses optical water classification (Moore et al. 2009). Initial results, to be confirmed. RRS (412) RRS (443)

  14. Ocean Colour CCI products Coverage: Global Projected Sensors and Periods In-situ Reference Data • MERMAID (MERIS Match up in-situ Data: 2007 - Present • MOBY (Marine Optical Buoy program):1996 - Present • NOMAD (NASA bio-Optical Marine Algorithm Data): 1997 – 2007 • SeaBASS (SeaWiFS Bio-optical Archive and Storage System):1997 – 2012 • AMT (Atlantic Meridional Transect):1995 – Present • AERONET-OC: 2001 – Present • Bedford Institute of Oceanography Bio-optical Database:1997 – Present • Boussole (Buoy for the Acquisition of Long Term Optical Time Series): 2005 - Present • ECMWF (European Centre for Medium-Range Weather Forecasts):1979 - Present
