The Global Sea Level Observing System (GLOSS) is an international programme conducted under the auspices of the Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM) of the World Meteorological Organisation (WMO) and the Intergovernmental Oceanographic Commission (IOC). GLOSS aims at the establishment of high quality global and regional sea level networks for application to climate, oceanographic and coastal sea level research.
The main component of GLOSS is the 'Global Core Network' (GCN) of over 290 sea level stations around the world for long term climate change and oceanographic sea level monitoring.
The GLOSS Station Handbook was constructed to provide further information on each of the tide gauges in GLOSS core network. It was updated during 2005 and these pages form Version 6 of the Handbook.
The Handbook includes references to individual countries and organisations that have made their sea level data (hourly values) available. Plots of annual mean sea level are also available for most sites and site maps are provided for many of the stations.
The Handbook also includes data from the:
