Data Buoy Cooperation Panel
DBCP Action Groups
• Independent self-funded body that maintains an observational
buoy programme in support of the WWW, WCRP, GCOS, and
GOOS.
• Good quality Data
• Real-time data on GTS
• Exchange information on activities and development
• Submit annual reports to the DBCP
 DBCP supports AG activities and may assist AG through DBCP
officers, Technical Coordinator, and WMO and IOC secretariats.

Data Collection & Distribution
• Moored buoys
– Inmarsat
– Meteosat, GOES
– Argos
• Drifting buoys
– Argos (location & data collection)
– GPS occasionally for location
Data Buoy Cooperation Panel
GTS Data processing
• For buoy data collected via Argos
GTS distribution via a dedicated sub-system:
– No interference with Argos users’ needs
– Flexible system capable of processing almost any kind of binary
format
– Wide range of calibration curves
– Simple Automatic QC checks

Quality Control Guidelines
• Decided at DBCP-7, Oct. 91
• To rationalise & speed-up
 status change process
 of buoys reporting on GTS
• Incorporated as part of WWW (Nov. 92, CBS-X)
• Principles :
 Met. Centres in best position for QC
 PIs and Met. centres share responsibility of QC
 DBCP-TC acts as a focal point
 Argos is responsible for elimination of gross errors
