Sea level measured by tide gauges from global oceans as part of the Joint Archive for Sea Level (JASL) since 1846

Metadata Updated: December 4, 2020

This collection contains the complete holdings of the Joint Archive for Sea Level (JASL) for hourly and daily data that have been quality controlled, assessed, and documented. Data are given in text files.

JASL is a collaboration between the University of Hawaii Sea Level Center/Joint Institute for Marine and Atmospheric Research and the National Centers for Environmental Information (NOAA/NESDIS/NCEI). It continues to acquire, quality control, manage, and distribute sea level data as initiated by the Tropical Ocean Global Atmosphere Program, which ended in 1994. The JASL is a Global Sea Level Observing System archive center and is the largest global collection of quality-controlled hourly sea level. The JASL receives hourly data from regional and national sea level networks. The data are inspected and obvious errors such as data spikes and time shifts are corrected. Gaps less than 25 hours are interpolated. Reference level problems are referred back to the originator. If the originators can not resolve the reference level shift,comparisons with neighboring sites or examination of the hourly residuals may warrant an adjustment. Descriptive station information and quality assessments are prepared. The objective is to assemble a scientifically valid, well-documented archive of hourly and daily sea level values in standardized formats. The JASL set is bi-annually updated and submitted to NCEI and the Permanent Service for Mean Sea Level.
