GeoTiff datasets of significant wave height (hs) in Greater North Sea and Celtic Seas calculated for the period 2000-2005 with a raster cell size of 300m - Numbers in the Geotiff names refer to the percentiles, e.g hs100.tif is the maximum wave height or the 100th percentile and it includes all values, whilst hs90.tif contains the 90th percentile wave height values obtained when the highest 10% of values are excluded. Units are in meters.
The layers are built using data from National Oceanographic Centre (NOC) wave model (ProWAM at a resolution of 12.5km) offshore. A high resolution (~300m) bespoke wave model based on the DHI Spectral Wave model was used to augment the coastal areas where the ProWAM model resolution was inadequate.
