Intercomparison and Validation TT

IV-TT-img Forecast accuracy of GOV systems in 2013
New metrics: Radar chart synthesis from the statistics of validation against observations and intercomparison of 5 operational global forecasting systems during 2013 Scores for 4 Ocean Essential Variables are provided along the four axes, normalized by the largest error

The team coordinates and promotes the development of scientific validation and intercomparison of operational oceanography systems. It pursues intercomparison activities developed during GODAE (Intercomparison working group) to quantitatively evaluate methodologies to judge the strengths and weaknesses of ocean analysis and forecasting systems.

Activities include the definition of metrics to assess the quality of analyses and forecasts (e.g. forecast skills) both for physical and biogeochemical parameters and the setting up of specific global and regional intercomparison experiments.





Meetings and workshops

Workshop 2011 (in collaboration with the OSEval-TT)

Workshop 2016 (Montreal)


Other activities

→ Monitoring and demonstration (at present from Class-4 assessment) (2016)
→ Participation in the CLIVAR-GSOP Workshop on Ocean Synthesis and Air-sea flux evaluation (WHOI, USA, 27-30 Nov 2012)
GOV-GSOP-CLIVAR Reanalysis Intercomparison Workshop , July 2013
GOV-GSOP-CLIVAR Reanalysis Intercomparison activity (login required)


The team liaises with the JCOMM ET-OOFS team for operational implementation. It will develop cooperation with CLIVAR/GSOP for climate issues (see above).

The IV-TT is co-chaires by:

  • Fabrice Hernandez, Mercator-Ocean, France and
  • Gregory Smith, Environment Canada.

Their contact information can be found on the Contacts page.
