We provide return level data used for the assessement coastal hazards of Medicanes in the upcoming article "Coastal hazards of tropical-like cyclones over the Mediterranean Sea". For both significant wave height at 20m depth and coastal sea surface elevation, return levels are provided at 10 year (RLs_10year.mat) and 100 year (RLs_100year.mat) return periods. Each .mat file, contains the following variables: - latitude/longitude: coastal point for the Mediterranean basin and islands within it; Dim = [7784,1] - elev_Rea,Hs_Rea: return levels computed for the present climate; Dim = [7784,1] - elev_Hist, elev_Rcp85, Hs_Hist, Hs_Rcp85:return levels computed for the historical asnd projected climate (from the 20 GCMs model used, see article); Dim = [7784,20]
