Statement

Continuous hourly time-series of significant wave height (Hs), peak (Tp) and mean (T02) wave period, and peak wave direction (Dir), directly offshore of Porsmilin in approximately 15 m water depth. Wave parameters were derived from sea-states hindcast databases (HOMERE and NORGAS-UG) developed by Ifremer at the node point 47554 (48°20'47.76"N, 4°40’52.32”W). Lat/long are referenced to WGS84. Databases are based on Wavewatch III (WW3) model (version 4.11) using the same unstructured grid covering the English Channel and Bay of Biscay with a resolution at the coast of 200 m. Wave parameters from the two databases were combined to form one continuous wave dataset over the period January 2000 - December 2019. Using model-buoy comparisons show that HOMERE and NORGAS-UG both demonstrate overall excellent skill modelling inshore waves, particularly for Hs, with R values constantly above 0.97. Agreement with in-situ data decreases slightly for Tp, T02 and Dir.
