The dataset consists of significant wave heights (Hm0), peak and second moment wave periods, sea surface wave directions, friction velocities, bottom orbital peak frequencies, velocities, directions, and periods (second moment). The dataset is a gridded dataset, with grid resolution of 1/9th x 1/6th degree, i.e. approximately 12 km. It covers the Northwest European continental shelf ranging from 48 to 63 degrees latitude and -12 to 13 degrees longitude. The data are 1 hour averages and cover the period from 01 January 1999 to 31 December 2008. The dataset was generated by the Wave Modelling (WAM) model run by the National Oceanography Centre (NOC) Liverpool. It was funded by the Aggregate Levy Sustainability Fund (ALSF) under contract MEPF 09-P114 and Natural Environment Research Council (NERC) National Capability (NC) funding. The dataset consists of 120 data files in Climate and Forecast (CF) compliant NetCDF format.
