An update to a Regional Frequency Analysis to Global Extreme Sea Levels output data

This dataset contains local extreme water levels derived from the updated Global Coastal RFA. It represents extreme water levels across multiple return periods at approximately 1 km resolution along the global coastline (excluding Antarctica). The data combines contributions from tides, storm surge, waves, and regional mean sea level. Vertical reference is EGM08. Return levels represent present-day conditions, based on a 19-year period centred on 2011. Further methodological details are provided in the accompanying manuscript.
