Several large regional observing activities or finite lifetime process studies, already exist or are planned in the Western Pacific.
With several substantial activities by different national groupings in the Western Pacific, TPOS 2020 seeks to coordinate these activities through a Western Boundary Task Team so that the whole can be more than the sum of the individual pieces. In addition to the goals of integration and increased collaboration, this task team seeks to help strengthen regional and national activities by placing them within the larger global context and utilize international guidelines for data policy and sharing.
This group will take advice on a project to be conducted in the Western Pacific. Once underway they will advise on mechanism for the project’s development and oversight.

The goal of the WP-TT is to identify the significant features of the western Pacific circulation and air-sea exchange, and to oversee and develop an integrated strategy towards an observing system that resolves these features for the purpose of applications of the ocean observing system (e.g. typhoon forecasting, climate forecasting and research) The main Terms of Reference are:
- Foster interaction and collaboration between the TPOS and other international programs that have an observational focus in the tropical western Pacific region, in particular WESTPAC and CLIVAR.
- Determine the observational requirements for over the next few decades, including time and space scales that should be resolved, through Backbone-TT contributions, or specialised/pilot contributions to TPOS, such as SPICE, NPOCE, ITF and other relevant projects.
- Develop observational strategies and design plans for the region, taking into account, as appropriate, the readiness of technology and feasibility of measurements, the evolving Backbone Observing System, existing activities, and guidance being developed by other TPOS 2020 Task Teams.
- Provide guidance as required to the Backbone Task Team and, as required, other Task Teams on strategies and plans for the region.
- Seek mechanisms for improved cooperation and coordination of logistics and ship time for the region, with the initial focus being on the evolution of the Western Pacific mooring contributions (e.g. TRITON, NPOCE, etc).
- Provide guidance on implementation and explore potential opportunities to engage with and collaborate with regional institutions for the implementation and maintenance of TPOS and its national components, and to evolve process-oriented boundary region measurements towards a sustained system.
- Promote and ensure that public data availability and distribution plans are included in all proposed observational efforts.
Several large regional observing activities or finite lifetime process studies, already exist or are planned in the Western Pacific. These include:
- Regional circulation observing activities north and south of the Equator:
- Indonesian Throughflow observations
- The Integrated Marine Observing System (IMOS; sustained)
- The Chinese Academy of Sciences (CAS) Project, 2014-2018.
In the North Pacific, a group of Chinese scientists have proposed a 10 year western Pacific observation proposal (led by Dake Chen and Weidong Yu) to the Ministry of Science and Technology (MOST) , which mainly consists of a “big cross” of moorings; meridionally near 135E (from TAO/TRITON to 24N), and zonally at 19N (150E and westward). The motivation for the activity is focussed on the Western Pacific ocean circulation, the East Asia monsoon, typhoons and ENSO. It is hoped that, if successful, there is potential for SOA to take it on as a sustained activity.
China also has 12 ocean satellite missions planned over the timeframe of the Western Pacific observation experiment.
With several substantial activities by different national groupings in the Western Pacific, TPOS 2020 should seek coordination so that the whole can be more than the sum of the individual pieces, and there would be benefit to all by joining these activities together as an integrated whole, including connecting up the science rationale. Such integration may raise opportunities for greater collaboration, and could also lead to discussions about what a sustained regional observing system for the Western Pacific could look like post 2020. Putting regional and national activities into the bigger picture may also help strengthen data sharing and regional agreements on data policy in line with international guidelines.
Form a Drafting Group to gather information on existing and planned activities and, subject to the Steering Committee’s consideration of the Group’s assessment of the above, begin drafting of instructions for a Task Team or other mechanism to oversee development of a project in the Western Pacific (Ken Ando, by end of February 2015
The Steering Committee noted that such an initiative is likely to have two phases, one coinciding with the TPOS 2020 timeline, the other post-2020.
Ken Ando agreed to lead the Drafting Group, with Dake Chen, Weidong Yu, Dongchull Jeon, Sophie Cravatte and Billy Kessler agreeing to assist. Several other regional experts were identified as potential contributors to the draft.
