The SC will provide scientific and technical oversight for the planning, system design, and implementation of the TPOS. This group will assess the evolving set of requirements through dialogue with relevant users and stakeholders, and coordinate a set of (pilot) projects designed to test and evaluate options. The SC will assess potential technology options for delivering a more effective and efficient TPOS including relevant scientific/expert panels and bodies. Together with the Resources Forum, the SC will manage communication and reporting.

Terms of Reference
Starting with the background and context provided above, guidance from the TPOS whitepapers and other available reports, and taking into account both existing and near horizon capabilities:
- Formulate a practical observing strategy and technical sampling requirement to ensure comprehensive air-sea fluxes can be estimated at hourly or better resolution across a set of key ocean and climate regimes in the tropical Pacific, covering the full suite of state variables to estimate heat, moisture, and momentum exchanges, including through use of bulk formula.
- The Context provides a number of suggestions on possible regimes that the TT may use as a basis for identifying around five regimes with distinct characteristics.
- Develop recommendations about measurements that should resolve the diurnal cycle in the oceanic and atmospheric boundary layers.
- Consider whether a subset of regimes where direct eddy-correlation approaches might be used is feasible and of value.
- Liaise with the existing and developing ocean satellite and modelling community on efficiently meeting their present and future requirements for ocean surface data.
- Engage biogeochemical and ecosystem experts to ensure the needs of key gas exchange calculations are met.
- Liaise with the other TPOS 2020 Task Teams to maximize logistical and scientific synergies.
Carry out a risk analysis of the proposed approach (e.g., dependency on a single satellite mission or communications systems or ship time) and suggest possible mitigation strategies (e.g., some redundancy).
The Task Team will report to the TPOS 2020 SC and complete the initial phase (refinement of goals, initial plan, key questions) of its work by October 2015.
