Ensuring Sea Level Data Quality and Dissemination

Researchers at the University of Hawai‘i Sea Level Center (UHSLC) continue to ensure that tide gauge data from nearly 500 stations maintained by 65 international agencies around the world (including more than 80 that are maintained by UHSLC) are collected, quality assessed, distributed, and archived for use in environmental monitoring and research applications related to climate. The UHSLC focuses on the stations that constitute the IOC/UNESCO Global Sea Level Observing System (GLOSS) and the Global Climate Observing System (GCOS). The UHSLC is a primary data center in GLOSS, curating and distributing two sea level gauge datasets: the Fast Delivery dataset and the Research Quality dataset. In addition, because vertical land motion monitoring is recommended by GLOSS/GCOS for the proper attribution of local sea level changes, the UHSLC maintains continuous GPS receivers at 11 stations.
