This is an archive of model output from the Regional Ocean Modeling System (ROMS) with two grids and two-way nesting. The parent grid resolution (referred to as Doppio) is 7 km and spans the Atlantic Ocean off the northeast United States from Cape Hatteras to Nova Scotia. The refinement grid (referred to as Snaildel) focuses on Delaware Bay and the adjacent coastal ocean at 1 km resolution. This ROMS configuration uses turbulence kinetic energy flux and significant wave height from Simulating Waves Nearshore (SWAN) as surface boundary conditions for turbulence closure.Ocean state variables computed are sea level, velocity, temperature, and salinity. Also inclued are surface and bottom stresses, as well as vertical diffusivity of tracer and momentum. 

The files uploaded here are examples of one time record from each of this dataset. Outputs for the full reanalysis, which comprises 14 Terabytes of data, are made available for download via a THREDDS (Thematic Real-time Environmental Distributed Data Services) web service to facilitate user geospatial or temporal sub-setting.
