| summary: | The Joint Archive for Sea Level (JASL) Research Quality Data Set (RQDS) is a collaboration between the University of Hawaii Sea Level Center (UHSLC) and the World Data Center for Oceanography of the National Centers for Environmental Information (NCEI), National Oceanic and Atmospheric Administration (NOAA). The objective of the JASL RQDS is to assemble a well-documented, quality-controlled archive of hourly and daily sea level values that is appropriate for scientific research applications. The JASL RQDS is the largest global collection of quality-controlled hourly sea level data, and ongoing efforts seek to acquire new sites and uncover historic records as available. |
| processing_level: | The JASL receives hourly data from regional and national sea level networks operating world-wide. JASL RQDS data undergo a level 1 quality assessment focused on variability (e.g., unit and timing evaluation, outlier detection, combination of multiple channels into a primary channel, etc.) followed by a level 2 quality assessment focused on datum stability (e.g., tide gauge datum evaluation, assessment of level ties to tide gauge benchmarks, comparison with nearby stations, etc.). |
| acknowledgment: | The JASL/UHSLC Research Quality Data Set is supported by the National Oceanic and Atmospheric Administration (NOAA) via the National Centers for Environmental Information (NCEI) and the Office of Climate Observations (OCO). |
