Climate Variability and Predictability (CLIVAR)
BODC has two distinct roles for CLIVAR. BODC manages both the Moored Instrument Data Assembly Centre and the Delayed-mode Sea Level Data Assembly Centre for CLIVAR. The two Data Assembly Centres (DACs) have responsibility to
- Obtain CLIVAR moored instrument and sea level data
- Convert data to a common format (netCDF)
- Quality control the data
- Assemble comprehensive metadata and documentation describing the data
- Ensure the data are properly managed and stored for the long term
- Collaborate with the other CLIVAR DACs to ensure integration across data streams
- Disseminate the data by making it available online to the CLIVAR and wider scientific communities
Moored Instrument Data Assembly Centre
The CLIVAR Moored Instrument DAC was launched at BODC in 2004. The previous Moored Current Meter DAC during WOCE was the Oregon State University Buoy Group which ceased operations as a DAC in August 2001. The Moored Instrument DAC deals with delayed mode time series data, rather than data from real time observing systems. The data handled include mainly current meters and ADCPs, but will also include various other types of moored instruments such as thermistor chains and sediment traps. The main contact for this DAC is Mary Mowat.
Sea Level Data Assembly Centre
The CLIVAR Delayed-mode Sea Level DAC has responsibility for delivering quality controlled and documented sea level data from approximately 150 tide gauges worldwide. This is a continuation of BODC’s role as the World Ocean Circulation Experiment (WOCE) Delayed-mode Sea Level DAC. The contact for this DAC is Elizabeth Bradshaw. This work is complemented by the operation of a 'fast-delivery' Sea Level Data Assembly Centre at the University of Hawai`i Sea Level Centre (UHSLC).
In addition, UHSLC and BODC, in collaboration with the Permanent Service for Mean Sea Level (PSMSL), act as data archiving centres for the Intergovernmental Oceanographic Commission's Global Sea Level Observing System (GLOSS).
