  Matthew Martin
• Assess the performance, quality and consistency
  of ocean forecasting and analysis systems.
• Observing System Evaluation Peter Oke Gilles
  Larnicol
• Assess the impact of observations on forecasts
  and analyses and improving the design of the
  global ocean observing system. (includes
  developing new approaches).

  Team Pierre Brasseur Nicolas Gruber
• Developing new strategies for the design and

8
Intercomparison and Validation

• Various intercomparison efforts of GODAE
  products to quantitatively evaluate methodologies
  to judge strengths and weaknesses of the
  forecasting systems e.g. MERSEA, basin-scale
  intercomparisons etc.
• European MERSEA Project in collaboration with
  other international
• GODAE projects has built a common methodology for
  real-time inter-comparison of forecast systems.
  Metrics are defined and aim at testing the
  consistency, quality and performance of each
  system (Class 1 to 4).
• Requires collaboration between modellers and
  interactions with user community to agree upon
  the definition of metrics which will be
  systematically used for assessing the quality and
  consistency of system outputs and the sharing of
  experience through critical analysis of
  inter-comparison exercises.

9
Intercomparison and Validation

• During IGST-XII (2007) it has been agreed to
  perform a demonstration
• of intercomparison among GODAE partners
• The main objectives were
• to demonstrate operational ocean systems in
  action
• to assess the quality of hindcast ocean products
• to perform intercomparisons among the different
  operational centers
• to promote validation and intercomparison as part
  of future "ensemble multi model forecast"
  applications.
• Intercomparison exercise, in real time, during
  the Feb-April 2008, 3
• months period. Assessment relied on Class 1 and
  Class 2 metrics that
• were made available by each partner.

10
Observing System Evaluation

• GODAE OceanView systems are powerful means to
  assess
• the impact of the global observing system,
• to identify gaps and
• to improve the efficiency/effectiveness of the
  observing system.
• OSEs or OSSEs are
• useful tools which have been applied to
  high-resolution ocean forecasting,
• seasonal-to-interannual prediction, and climate
  analysis and reanalysis
• OSEs are flexible tools as they can be used to
  examine the impact of
• observations on a particular application (e.g.
  surface current forecasts
• for marine safety applications) or to give
  insight into the effectiveness of
• the data assimilation systems that are being
  used

11
Observing System Evaluation

• OSEs and OSSEs ctd.
• Get the most out of observations
• - over- or under-fitting observations
• - system comparisons
• - information content of observations
• - refined obs-error/length-scale estimate
• - better assimilation procedures
• - identify instrument errors
• GODAE OceanView OSE Workshop (4-5 June 2009)
• Towards Routine Monitoring

12

  larger-scale systems in many coastal regions of
  the world ocean.

  of operational systems
• (ii) to further assess and demonstrate the value

  metrics to biogeo-
• chemical variables and to develop

• formulate relevant recommendations on these
  issues
• (v) to promote and organize educational
  activities (summer schools,
• training workshops, etc.) aimed at sharing
  experience between
• young scientists, operational oceanographers and
  marine ecosystem
• experts. Links with IMBER, GEOTRACES and
  SOLAS.

15
Marine Ecosystem Analysis and Prediction Task
Team

• So far has focused on 3 key areas
• (i) develop applications of GODAE products to
  ecosystem and biogeochemistry projects.
• (ii) specify requirements to integrate
  biogeochemistry and ecology into ocean data
  assimilation systems (e.g. need for improved
  representation of upper ocean processes such as
  turbulent mixing and vertical advection).
• (iii) design and improve the observing system for
  marine ecosystems and biogeochemistry
• Key findings and conclusions in a synthesis paper
  (Brasseur et al., 2009) and presented at 2008
  GODAE Symposium.
• 2009
• Revisit IMBER-GODAE working plan proposed in
  2007, taking into
• account the recommendations of the IGST, GOVST
  and ISSC.
• Organize second joint IMBER-GODAE OceanView
  workshop in
• early 2010 in order to review the progress
  made and elaborate a more
• structured framework of activities until
  2013.

Evolution of GODAE Systems

• Most GODAE groups have or are now transitioning
  towards operational or pre-operational status.
• GODAE systems need continuous improvements and
  should benefit from scientific technological
  advances in data processing, data serving,
  modeling and data assimilation (incl. evolution
  of the observing system).
• GODAE systems are also evolving to satisfy new
  requirements (e.g. coastal zone and ecosystem
  monitoring and forecasting, climate monitoring
  and reanalysis).
• Challenges require international collaboration
  and cooperation

19
New Societal Demands

• Integrated descriptions of ocean state and
  characterisation detection of climate change in
  the ocean
• Forecasting in shelf-seas coastal waters
• Monitoring and management of the marine
  environment (including biogeochemistry
  ecosystems)
• Development of improved weather climate
  predictions (near coasts, weather, tropical
  cyclones, monsoons, seasonal and decadal
  predictions)
• Assessments of uncertainty in downscaling climate
  change predictions to coastal regions
