Sea level measured by tide gauges from global oceans as part of the Joint Archive for Sea Level (JASL) from 1846 to 2019 (NCEI Accession 0019568)
The Joint Archive for Sea Level (JASL), a partnership 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), 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. Data files are in text format.

Supplemental Information | In this Accession, NCEI has archived multiple versions of these data. The latest version has the largest version number, in this case, 0019568v7.7. Some series in earlier versions have been corrected so it is important to use the most recent version, which also includes any new data added to the archive since the previous version was made. In this accession, NCEI has archived multiple versions of these data. The latest (and best) version of these data has the largest version number. |
Purpose | This dataset is available to the public for a wide variety of uses including scientific research and analysis. |
