Physical Model of the Mississippi Sound and Bight from 2016-07-14 to 2016-08-14 with Low-pass Filtered Meteorological Forcing

Model output of circulation, water mass and dynamical properties (currents, temperature, salinity, and sea level) for the Mississippi Bight and Mississippi Sound region of the northern Gulf of Mexico. The model application is newly developed as part of the GOMRI-funded CONCORDE consortium and has been configured with 400 m spatial resolution and 24 vertical layers. Observed freshwater input derived from available tide gauge stations are applied as riverine forcing, and the Naval Research Laboratory-Navy Coastal Ocean Model (NRL-NCOM) output at 1km was used as outer boundary condition forcing.

Surface atmospheric forcing is a low-passed (24-hour filtered) version of the 1 km hourly product that was also developed as part of the CONCORDE consortium’s modeling component (the CONCORDE Meteorological Analysis - CMA). This filtering removes high-frequency meteorological forcing, such as the diurnal sea breeze, allowing for scenario testing that reveals the impact of high-frequency winds on estuarine - shelf exchange. The model output provided in this dataset provides an hourly resolution of physical parameters (currents, temperature, salinity, water levels) for the time frame around the Summer 2016 sampling campaign of the CONCORDE observational teams (2016-07-14 to 2016-08-14).
