Permanent Service for Mean Sea Level (PSMSL)

摘要

Since 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 at the National Oceanography Centre (NOC), which on the 1st November 2019 began operating as an independent self-governing organization - a charitable company limited by guarantee. Funding is provided by the UK Natural Environment Research Council (NERC). The PSMSL continues to be one of the main data centres for both the International Association for Physical Sciences of the Oceans (IAPSO) and the IAG. The PSMSL operates under the auspices of the International Science Council (ISC) and reports formally to IAPSO's Commission on Mean Sea Level and Tides. The PSMSL is a regular member of the World Data System of ISC.
