Water Level Climatologies for Pacific Island Countries

Components of total hourly sea level signal, monthly exceedance probabilities, and gridded tides and sea level anomaly. The data collection comprises ~4 GB, >10000 files comprising processed hourly sea level files, weekly averaged altimetry files, and derived gridded products. Access to this data collection is restricted and relies on scripts. Please phone or email the contact person for this data collection to discuss access to the data.

Lineage: Post processed data files for analysis of sea level contributions on hourly, seasonal and interannual time scales.

Credit: Tide gauge data provided by Australian Bureau of Meteorology and the University of Hawaii. Global tide model provided by Oregon State University; satellite altimetry provided by Ssalto/Duacs and distributed by Aviso. This data collection is a product is funded and supported by the Australian Government through the Pacific Australian Climate Change Science and Adaptation Planning Programme (PACCSAP). PACCSAP was funded by Department of Foreign Affair & Trade, managed by the Department of the Environment and the science was delivered by the partnership between CSIRO and the Bureau of Meteorology.

This output was produced as part of PACCSAP Project 1.4.4: Effect of climate change variability and change on extreme sea levels and coastal impacts.

Project Description: This activity builds on extreme sea level research undertaken during the PCCSP. Historical extreme sea level events known to cause erosion and inundation will be analysed at selected locations across the Pacific. Projections of extreme sea level events will be assessed for Fiji and Samoa. Wave transformation during extreme sea level events will be examined across Funafuti atoll (Tuvalu).
