Gumbel parameters Global Tide and Surge Reanalysis (GTSR) dataset

GTSR (Global Tide and Surge Reanalysis) is the first global reanalysis of storm surges and extreme sea levels based on hydrodynamic modelling. GTSR covers the entire world's coastline based on the DIVA coastline segmentation. To estimate the probabilities of extreme sea levels, we apply extreme value statistics using the annual maxima method. For each output location, we extract the annual maximum for the calendar years 1979–2014 and fit a Gumbel distribution using the maximum-likelihood method. This files provides the location and scale parameters.
