WAVEWATCH III® Production Multigrid: July 2013 to present


The multigrid production uses the multi-grid spectral wave model WAVEWATCH III® version 4.15, with operational NCEP winds and ice fields as input forcing fields. No wave data assimilation is performed. The model is run four times a day, with all available data.

Multigrid Model Setup

Model Grid Descriptions

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.
