The multigrid production hindcast uses the current operational multi-grid spectral wave model WAVEWATCH III® with operational NCEP winds and ice fields as input forcing fields. No wave data assimilation is performed. The model is run after the end of the month, with all available data. Output is available from February 2005 to September 2018.
The wave model suite consists of 9 rectilinear global and regional nested grids. These grids were developed using ETOPO-1 bathymetry (Amante and Eakins, 2009), together with v1.10 of the Global Self-Consistent Hierarchical High Resolution Shoreline (GSHHS) Database. The higher-resolution grids have been masked to improve model efficiency, and only provide data near shore. See Chawla and Tolman (2007,2008) for details on the software used for developing these grids.
