North Sea Quality-Controlled Sea Level Dataset

<strong>North Sea Quality-Controlled Sea Level Dataset</strong> comprises rigorously quality-controlled sea level observations from 29 tide gauge stations distributed across the North Sea region. The dataset includes original quality-controlled sea level time series, residual time series (with the tidal signal removed), and both high-frequency (T &lt; 2 hours) and low-frequency (T &gt; 2 hours) components. Data are provided at temporal resolutions ranging from 1 to 15 minutes, covering the period specified for each individual station.<br>This dataset supports the forthcoming publication <em>"</em> <em>Investigation of North Sea high-frequency sea-level extremes using long-term sea level measurements" </em>(Mia Pupić Vurilj, Gozde Guney Dogan, Marijana Balić, José A. A. Antolínez, Jadranka Šepić; to be submitted to <em>Natural Hazards</em>) and is made publicly available to encourage its reuse in related scientific studies.<br>Comprehensive documentation of the data sources, quality control procedures, preprocessing methodology, and technical specifications is provided in the accompanying README.txt file.<br>The dataset can be used for multiple coastal and climate applications, as it provides long, quality-controlled, sub-hourly sea-level records. Some of key applications are:a) Analysis of storm surge events (timing, magnitude, duration) along the North Sea coastb) Detection and characterization of high-frequency oscillations (i.e. seiches, meteotsunamis)c) Assessment of coastal flooding, compound events and their impact on coastal risk
