British Oceanographic Data Centre's International sea level data system
Original (non-English) name
The data available in the International Sea Level data system are a combination of data collected under the Global Sea Level Observing System (GLOSS), the World Ocean Circulation Experiment (WOCE) and the Climate Variability and Predictability (CLIVAR) programmes.
This high frequency delayed-mode data set provides quality controlled data from stations in the GLOSS Core Network, the network identified by the CLIVAR programme for ongoing climate monitoring and the network identified by the Global Climate Observing System (GCOS).
The data assembly began with WOCE in early 1991 and continued until 2002. CLIVAR evolved from WOCE and started in 1995. Towards the end of the WOCE period BODC, jointly with the Permanent Service for Mean Sea Level (PSMSL), became a GLOSS data archiving centre.
BODC is responsible for constructing the data set suitable for archiving and long-term preservation and handles hourly (or sub-hourly) values, together with ancillary variables (e.g. atmospheric pressure) where these are available.
