History & achievements


• 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.

DBCP Action Groups

Status by country

Status by variable


Data Collection & Distribution

• Moored buoys

– Inmarsat– Meteosat, GOES– Argos

• Drifting buoys

– Argos (location & data collection)– GPS occasionally for location


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 Gross error limits User limits Checksum & compression index by sensor All bits identical Sensor blockage


GTS data processing• Argos GTS sub system, also:

– Data encoded according to WWW standards:

o BUOY Drifting and moored buoyso SYNOP Land stationso SHIP Ship reportso BATHY XBTs (temperature/salinity profiles)o TESAC Temperature/Salinity/Current profileso HYDRA Hydrological stationso BUFR Binary table driven code

– Multiplexing methods for large amount of data– Geo magnetic variation correction for wind direction– Reduction to sea level for land stations– Dew Point Temperature computation– Processing of GPS positions


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

• For DBCP and AG

• In support of Global and National programmes

• Included in GOOS/GCOS implementation strategy

• Autonomy of Action Groups recognized

Implementation Strategy


• The strategy:

o Climatology of drifter tracks

o Development of deployment & reseeding strategy

o Promote development on new buoys & sensors

o Encourage buoy operators to join

o Monitor data-flow

o Negotiations with manufacturers & telecom. Systems

o Focus for information on new telecom systems

o Sensor evaluation trials
