Joint Workshop of the OS-Eval TT and CP-TT and SynObs Kick-Off

Invitation

The Observing System Evaluation (OS-Eval TT) and the Coupled Prediction (CP-TT) Task Teams of OceanPredict are organising a joint workshop on

15-18 November 2022

at the Tsukuba Center for Institutes, and JMA/MRI Building, Tsukuba, Japan.

At this workshop we are planning to officially kick-off the project of the UN Decade of Ocean Science, Synergistic Observing Network for Ocean Prediction (SynObs).

 

Attendance

Other than the members of the two task teams (OS-Eval TT and CP-TT), participation is also encouraged from

  • Everyone who intends to participate in or to contribute to SynObs.
  • Attendees of previous meetings of either task team.
  • OPST and OPAS members.
  • Researchers who work in earth system predictions based on ocean data assimilation or evaluation/design of observation networks.

Organisation

A joint Workshop of the Observing System Evaluation Task Team (OS-Eval TT) and the Coupled Prediction Task Team (CP-TT) of OceanPredict

The workshop will be held as a hybrid event (in-person at the Tsukuba Center for Institutes or JMA/MRI Building and online). We will have on-site and online oral presentations, including invited talks, and poster presentations. The hosts will provide meeting facilities (meeting rooms, web meeting application, etc.) More details about on-site lunches and breaks, and information about Covid measures will be provided in time to all those who plan to attend in person. Being on-site might include requests of hand sanitisation and mask protocols. The meeting will also use a web meeting application to allow remote participation.

If the pandemic gets worse to a serious level again, the onsite event will be cancelled, and the meeting will be held fully virtual. More information will be provided in a later announcement.

 Where: Tsukuba Center for Institutes, Tsukuba, Japan (near Tokyo)
 When: 15-18 November 2022
 Duration: 4-day meeting

Hosted by the

Japan Meteorological Agency (JMA)/ Meteorological Research Institute (MRI)

Japan Agency for Marine-Earth Science and Technology (JAMSTEC) /Research

Institute for Global Change (RIGC)

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.

Objectives/goals

  • To emphasize the importance of ocean observing co-design/evaluation and data assimilation development for more effective use of ocean observation data.
  • To promote developments for increasing oceanic impacts in earth system predictions.
  • To share the objectives/goals of SynObs and to set up SynObs activities.

Agenda and workshop themes

The workshop will cover four sessions featuring science presentations and posters with discussions. We are seeking submissions of abstracts for all sessions (oral and poster).

The objectives of the workshop include:

  • To emphasize the importance of ocean observing co-design/evaluation and data assimilation development for more effective use of ocean observation data.
  • To promote developments for increasing oceanic impacts in earth system predictions.
  • To share the objectives/goals of SynObs and to set up SynObs activities.

1.  Co-design and evaluation of ocean observing systems: their needs and achievements

1A. Expectation of co-design/evaluation from observational communities
  • What observing systems need co-design/evaluation
  • What are the benefits from co-design/evaluation
1B. Observing System Evaluation showcase
  • Evaluation of large swath sea level anomaly data (SWOT, COMPIRA, …)
  • Evaluation of the global Argo Array and its evolution (Including Core Argo,  BGC Argo, Deep Argo, etc.)
  • Evaluation of tropical buoys (TPOS2020 design etc. )
  • Other ocean observing systems and platforms
1C. Methodology
  • Strategy for Multi-System OSE/OSSE and Nature Run
  • New methods for designing and evaluating the observation network
  • Evaluation of societal and economical impacts
  • Best practices for observing system evaluation

 

2.  Data assimilation development for better use of observation data

2A. Observation operators
  • For new-type observations (Lagrangian trajectories, Ocean current velocities, etc.)
  • For coupled data assimilation systems (Radiance, Scatterometer, etc.)
2B. Modeling of the background errors across multi-physics/domains
  • Across the atmosphere-ocean boundary
  • Across the open ocean-coastal sea boundary
  • Across physical and biogeochemical parameters
2C. Methods for dealing with correlated observation errors
  • Data Thinning and modeling of observation errors

 

3.  Ocean modeling and initialization in earth system predictions

3A. Modeling, and data assimilation of the ocean-atmosphere boundary layers
  • Impact of Wind waves
  • Vertical mixing process at the boundary
  • Variation of Skin-SST
  • Exchange of momentum, heat, and fresh-water flux
3B. Best practices for earth system predictions
  • Coupled data assimilation for earth system predictions
  • Initialization technique to reduce the coupled shock
  • Oceanic perturbation for ensemble member generation
  • Operational design for earth system predictions
  • Metrics to assess the oceanic impacts
3C. Roles of ocean observation data in earth system predictions
  • Ocean Observation impacts
  • Ocean observation timeliness requirements

 

4.  Discussion on the future activities of OS-Eval TT, CP-TT, and SynObs

  • Setup of SynObs activities
  • CP-TT contribution to UN Decade of Ocean Science (ForeSea and SynObs)
  • Enhancing communication across ocean and coupled predictions and observational communities for more effective use of the ocean observation data

Registration and abstract submission

You can register and submit an abstract(s) for the Joint Workshop of the OS-Eval TT and CP-TT by completing the Registration and abstract submission form (link below). If you only want to register but not submit an abstract, just leave the respective submission form part blank.

The policy of the host (JMA/MRI and JAMSTEC/RIGC) will be respected with regard to  acceptance of participation.

Registration and abstract submission will be open in mid- June, 2022, and close on

15 July 2022

We encourage all non-Japanese abstract submitters who plan to attend in person to register and submit their abstract at their earliest convenience.

Everyone without a Japanese passport will need a Japanese business visa to enter Japan. We will provide on-site participants from foreign countries with an invitation letter, which is necessary for the visa application. Please keep it in mind that you need to communicate with the host in August to submit information on your air carrier, trip dates, etc. which is required for issuing the invitation letter.
