A 30-year wave climatology has been generated with the NOAA WAVEWATCH III® using the Ardhuin et al (2010) physics package, 15 regular lat-lon grids, and the NCEP Climate Forecast System Reanalysis and Reforecast (CFSRR) homogeneous dataset of hourly high-resolution winds. The time period covers from 1979 through 2009.
* Important Note: The Phase 2 Hindcast data set was recently moved from our FTP server to our web server. Please update your bookmarks and links as needed with the new location.
Some browsers (Firefox, Chrome) may try to display the contents of a GRiB file in the browser window instead of downloading it. If that happens, right-click on the GRiB file link and select "Save Link As..." to download the file.
The model was run with the Ardhuin et al (2010) source term package (ST4) which includes the flux computation in the sources (FLX0, STAB0). Additionally, the model uses a third order propagation scheme (UQ), with no damping or scattering by sea ice (IC0, IS0), and no reflection (REF0).
The wave model suite consists of global and regional nested grids. The rectilinear 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.
Note: Model was run using the Global (glo_30m) and Arctic Ocean (aoc_15m) grids, but the results are interpolated onto the glo_30m_ext (and not given on the other two grids).

There is a problem extracting data from the Mediterranean GRiB files,
where the longitude values are incorrect.
Here is an example Python script to work around the problem.
