Permanent Service for Mean Sea Level (PSMSL)

External Data Reference
Established in 1933, the Permanent Service for Mean Sea Level (PSMSL) has been responsible for the collection, publication, analysis and interpretation of sea level data from the global network of tide gauges. It is based in Liverpool at the National Oceanography Centre (NOC), which is a component of the UK Natural Environment Research Council (NERC). The PSMSL is a member of the Federation of Astronomical and Geophysical Data Analysis Services (FAGS), which is currently restructuring under the World Data System . Funding for the PSMSL comes from FAGS, the Intergovernmental Oceanographic Commission (IOC) and NERC.

Indicators using this data

Global and European sea-level rise Global and European sea-level rise This indicator comprises several metrics to describe past and future sea-level rise globally and in European seas. Global sea-level rise is reported because it is the second-most important metric of global climate change (after global mean surface temperature), and because it is a proxy of sea-level rise in Europe. Past sea-level trends across Europe are reported in two different ways: first, absolute sea level change based on satellite altimeter measurements that reflect primarily the contribution of global climate change to sea-level rise in Europe; second, relative sea-level change based on tide gauges that also include local land movement, which is more relevant for the development of regional adaptation strategies. The following components on observed sea-level rise are included: Change in global mean sea level (time series starting in 1880, in mm), based on a reconstruction from various data sources (since 1880) and on satellite altimeter data (since 1993) Trend in absolute sea level across Europe (map, in mm/year), based on satellite measurements (since 1992) Trend in relative sea level across Europe (map, in mm/year), based on selected European tide gauge stations (since 1970) Furthermore, this indicator presents projections for sea level rise in the 21st century, both globally and for the European seas. The indidator also presents the contributions to past and future global sea level rise from different sources. Finally, the indicator presents information on observed and projected changes in extreme sea level along European coasts. However, due to insufficient data availability this information cannot be presented by means of figures or maps.
