Gulf of Mexico NCOM 1 km resolution numerical model simulation, September-December 2015

The numerical model is the Navy Coastal Ocean Model (NCOM) (Barron et. al, 2006). The circulation model output includes temperature, salinity, velocity(currents), surface elevation, wind velocity, atmospheric pressure, surface fluxes and sound speed in the Gulf of Mexico during the CONCORDE survey time period from September through December 2015, i.e. before, during and after the CONCORDE Fall Cruise period. The domain is forced by boundary conditions from the global operational HYCOM. The vertical setup uses 34 sigma levels (above 250 m) and 16 Z levels beneath (50 total levels). This model experiment was forced hourly by Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS). Tidal potential forcing is applied to the inner domain, and tidal boundary conditions for water level and barotropic velocity are provided by the Oregon State University global Ocean Tide Inverse Solution (OTIS). Data assimilation is used in the experiment. River forcing is based on monthly climatological observed transports. This dataset was created by the CONsortium for oil exposure pathways in COastal River-Dominated Ecosystems (CONCORDE). This research was made possible by a grant from BP/The Gulf of Mexico Research Initiative.
