1. What are the needs for advancement of the ocean observing system?
(a) Long-tem Goals
(b) Current status
(c) Short-term increments

(a) Goals:
• Accuracy for net heat flux estimates: ±10Wm-2
• Balanced global energy budget

(b) Current status of global air-sea flux measurements:
There are needs for
• better spatial coverage, particularly at higher latitudes
• high quality, continuous record, long duration
• simultaneous measurements of wind, wave, radiations in addition to humidity, temperature, and precipitation
All components No QLW
x No QLW and QSW

Satellite radiation products: discontinuity in both space and time
There is a need of radiation (longwave and shortwave) sensors at reference sites and along cross-basin VOS sections.

(c) Short-term increments
• Review flux observing capacity on existing platforms (buoys, research vessels, VOS, coastal guard/icebreakers…)
• Improve efforts to install radiation sensors on all buoys
• Improve efforts to install air-sea flux sensors on major cross-basin VOS

2. What are the needs of the ocean observing and user communities?
(1) High frequency sampling (at least 3-hourly, ideally 10-minute)
(2) Error bar information for flux measurements and analysis products

3. What are the recommended priorities for the Climate Observation Program?
• Review existing flux observing capacity on existing platforms (buoys, research vessels, coastal guard/icebreakers…)
• Improve efforts to install radiation sensors on all buoys, air-sea&flux sensors on arctic research vessels, icebreakers, major cross basin VOS
• Reenergize a flux workgroup to focus on review and strategic planning and to prepare for OceanObs (2008?)
