International sea level: British Oceanographic Data Centre (BODC)

The international sea level data available on the BODC website are a combination of data collected under the 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

1. The GLOSS Core Network
2. The network identified by the CLIVAR programme for ongoing climate monitoring
3. The network identified by the Global Climate Observing System (GCOS)

The data assembly began with WOCE in early 1991 and continued until 2002. CLIVAR, evolving from WOCE, started in 1995 and will have a lifetime of 15 years. Towards the end of the WOCE period BODC, jointly with the Permanent Service for Mean Sea Level (PSMSL), became a GLOSS data archiving centre.
