Modeled oil particle trajectory fields from the GoM-HYCOM model (1/50 deg resolution) for selected periods following the Deepwater Horizon oil spill from 2010-04-20 to 2010-07-10

This dataset contains position, environmental data, and oil dispersal/weathering characteristics on model output from an open source ocean trajectory framework, OpenDrift, used to simulate the 2010 Deepwater Horizon (DWH) oil spill. OpenDrift includes the integrated oil drift module OpenOil, which includes a number of relevant processes, such as emulsification, wave entrainment, and droplet formation. This takes account of the actual oil type/properties, using the ADIOS (Automated Data Inquiry for Oil Spills) oil weathering database of National Oceanic and Atmospheric Administration (NOAA). Metocean forcing data are taken from the Hybrid Coordinate Ocean Model (HYCOM) in the Gulf of Mexico, GoM-HYCOM 1/50 degree, with realistic river input and European Centre for Medium-Range Weather Forecasts (ECMWF) products of wind and wave parameters with 1/8 degree resolution. The six included files contain output which verifies model performance by simulating conditions in April 2015 for comparison with field observations, compare the oil droplet size distribution parameterizations of Delvigne and Sweeney (1988) and Li et al. (2017), and compare conditions with and without freshwater input for two high river discharge events.
