Objective The Plan is in place GCOS-92: Initial GOOS GEOSS Ocean Baseline UNFCCC Priority G8 Commitment Implement the ocean domain of GCOS-92: Objective Tsunami Additional Drivers IPY IOOS, Regional GOOS

Initial Global Ocean Observing System for Climate The initial system is designed to meet Climate requirements, but it also supports: Weather prediction Global and coastal ocean prediction Marine hazards warning Transportation Marine environment and ecosystem monitoring Naval applications 8 of 9 Societal Benefits Tide gauge stations Drifting Buoys Tropical Moored Buoys Profiling Floats Ships of Opportunity Ocean Reference Stations Ocean Carbon Networks Arctic Observing System Dedicated Ship Support Data & Assimilation Subsystems Management and Product Delivery Satellites -- SST, Surface Topography, Wind, Color, Sea Ice

JCOMM Observations Coordination Group ADD the mission and objectives for the global component All six global in situ implementation programmes are linked internationally through the WMO-IOC JCOMM Observations Coordination Group. Together they are building a global ocean observing system. Satellite Remote Sensing Requirements Data Assimilation and Modeling Capacity Building Data Management PA Services PA

Observations Coordination Group (OCG) – 3rd session, 9-11 March 2009, Paris: Systems approach (funding, implementation, deployment, monitoring etc.) Non-climate requirements Integration of in situ and satellite observations Report by variable – network optimization

15 Essential Climate Variables Surface: Sea surface temperature, sea surface salinity, sea level, sea state, sea ice, currents ocean color, carbon dioxide partial pressure; Sub-surface: Temperature, salinity, currents, nutrients, carbon, ocean tracers, phytoplankton.

Observing System Status: 2008, Q4 Temperature Profiles Sampling requirements: 1 profile Every 10 days In every 3 x 3 º BATHY (mostly XBTs) TRACKOB (surface underway data) TESAC (mostly Argo floats) BUOY (moored and drifting) Requirement: All boxes blue Goal: 100% Global Coverage

OCG-3 (continued) Data – importance of metadata, QC, close to RT as possible! BUFR, ‘Cookbook for submitting data’ JCOMM catalogue of standards and best practices Research and operations as close as possible OceanObs’09 Observing System Support
