  1. Working Group on Surface FluxesLegacy IssuesElizabeth Kent National Oceanography Centre, Southampton

  2. WGSF Legacy Issues • Already in legacy period - so considering shorter term • Groups/organisations with ongoing interests in surface fluxes include: • GEWEX • SEAFLUX • Baseline Surface Radiation Network • Also others including LandFLUX, GPCP, ISCCP, SRB • OceanSITES: Flux reference measurements • SAMOS/IMOS etc: Routine measurements from RVs • US CLIVAR High Latitude Surface Flux Working Group • IGBP/SOLAS

  3. WGSF Legacy Issues: What is being covered and what may fall between the gaps? • Radiation • Land radiation measurement/monitoring by BSRN • Expansion to marine measurement is being done by individuals • Physical air-sea fluxes • Satellite air-sea fluxes are covered by SEAFLUX • SOLAS has focus 2 on the physical fluxes, but most activity e.g. all new initiatives in mid-term strategy and task teams are on the biogeochemistry • Precipitation • Satellite precipitation covered by GPCP and others • Measurement of marine precip. remains problematic and efforts to improve things remain ad hoc • Gases/aerosols/dust • SOLAS

  4. WGSF Legacy Issues: What is being covered and what may fall between the gaps? • Process studies / parameterisation • SOLAS has provided a framework for biogeochemical fluxes • Physical flux process measurement often on individual scientist/research group basis • Sustained flux measurements • OceanSITES is ongoing • Routine RV measurements may need to be co-ordinated internationally to build on the examples of good practice we already have (e.g. SAMOS/ IMOS)

  5. WGSF Legacy Issues: What is being covered and what may fall between the gaps? • Gridded flux datasets • Some datasets now have uncertainty estimates • SEAFLUX provides a portal for satellite physical flux products • No common portal for all types of flux products • Lack of information on characteristics and suitability • Model fluxes • SURFA project and portal set up • Interactions between observationalists and modellers probably need to improve • Data management • No common access to measured flux data • International data centre structure risks splitting flux-related variables

  6. WGSF legacy issues include: • Improve radiation measurement at sea, maintain links to BSRN • A co-ordinated approach to precipitation measurement at sea is needed to make progress • Lack of co-ordination for physical flux process studies & parameterisation improvement • Co-ordination of routine measurement by research and selected commercial vessels needed internationally • Interaction with modellers needs to be increased • Access to flux products needs to be improved • Guidance on suitability of flux products not typically available • Aggregation of, and common access to, flux measurements and improved data management highly beneficial
