Oceanweather are pleased to announce the completion of the updated GROW-FINE East Coast (GF-EC) wind, wave, and hydrodynamic hindcast covering the US Atlantic Ocean coastline. Winds and waves were modeled on a nested set of grids with a resolution of 5.6km on the finest grid, and were run in a continuous operational period for years 1979-2017, incorporating overlapping reanalyzed tropical systems. Separate storm hindcasts of significant tropical (1924-2017) and extra-tropical (1957-2017) storms have also been produced as part of the project using a finer archive timestep. In addition to wind and wave parameters, the tropical storm hindcasts contain water surface elevation and 2D depth-averaged velocity variables generated by the state of the art ADCIRC numerical model using OWI’s lightweight version of the NOAA operational HSOFS mesh (HSOFSR), with output archived on the same grid points as the winds and waves.

These data are suitable for a variety of uses in the metocean and offshore design fields, and are available for purchase by point or as a whole and in a variety of formats including statistical analyses. For more information, please contact Erin Harris via email at erinh@oceanweather.com.
