Cci ecv validation
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).


Requirements
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.


Cardinal requirement
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.



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

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


GCOS Requirements consultation process

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.
