Joint OS-Eval TT/ CP-TT Workshop

Organisation

Duration: 4-day meeting
Organisers: Yosuke Fujii (Co-chair of the OS-Eval TT, JMA/MRI)
Elisabeth Remy (Co-chair of OS-Eval TT, Mercator Ocean International)
Chris Harris (Co-chair of CP-TT, Met Office)
Santha Akella (CP-TT members, NASA)

Yuhei Takaya (CP-TT member, JMA/MRI)
Kirsten Wilmer-Becker (OceanPredict programme coordinator, Met Office)

Background

The main goal of the Observing System Evaluation Task Team (OS-Eval TT) under OceanPredict is the provision of ongoing demonstrations of the impacts of observations on global and regional ocean forecast and analysis systems.

The Coupled Prediction Task Team (CP-TT) wants to draw together the international scientific and technical expertise in ocean, sea-ice and wave prediction and to seek collaboration with equivalent expert groups in atmospheric-land surface-hydrology prediction to accelerate the scientific and technical development of fully coupled systems for short- to medium-range prediction. The CP-TT is planning to complement efforts of the atmospheric and seasonal communities in their exploration of coupled prediction, and to actively support exchanges between these communities.

Attendance

  • Members of the two task teams (OS-Eval TT and CP-TT) are warmly invited to the meeting, but also
  • Attendees of previous events of either team
  • OPST and OPAS members
  • Researchers who work in earth system predictions based on ocean data assimilation or evaluation/design of observation networks

    • Evaluation of tropical buoys and the TPOS2020 design
  • Evaluation of ocean data impacts on coupled prediction and data assimilation
  • Design of observation networks for obtaining synergy
    • Synergy from the combination of in situ and satellite data
    • Synergy from the combination of oceanic and atmospheric observations
    • Synergy from the combination of coastal observing networks
    • Synergy from the combination of physical and biogeochemical observations
 2 Development for effective use of observation data
  • Observation operators
    • For new-type observations (Lagrangian trajectories, Ocean current velocities, etc.)
    • For coupled data assimilation system (Radiance, Scatterometer, etc.)
  • Modelling of the background errors across multi-physics/domains
    • Across the atmosphere-ocean boundary
    • Across the open ocean-coastal sea boundary
