Nearfield Plume Hindcast of the Deepwater Horizon blowout from April 2010 to July 2010 using the Texas A&M Oilspill Calculator: Bent Plume Model

The data set is developed as a part of the simulations that carried out for the Hindcast of Deepwater Horizon (DWH) oil spill from 2010-04-22 to 2010-07-14 in the Gulf of Mexico. Model simulation results included in the data are from the near-field plume model in the Texas A&M Oilspill Calculator (TAMOC) that can be used to simulate under water oil and gas blowout plumes. The plume model namely the Bent Plume Model (BPM) is used for the simulations. Simulations are done hourly from 2010-04-22 to 2010-07-14 . Model input data are saved in “Input” folder in netcdf and .csv formats, and model results are saved in “Output” folder in netcdf format. The tools for reading and post processing of model results are included in the TAMOC modeling suite, which can be freely downloaded from https://github.com/socolofs/tamoc. Release fluid composition and parameters needed as input to the model are saved in the .csv files according to the format needed in the TAMOC modeling suite to read the data. Ambient data used are extracted from nodc.noaa.gov (in the DWH directory) for a location in the Gulf of Mexico close to the Deep Water Horizon spill location. They are saved in the folder Input/NOAA according to the format used as input to TAMOC. Each ambient data file is corresponding to each hour of simulation starting from 2010-04-22, 00th hour to 2010-07-14, 23rd hour. The simulations are carried out for the whole time duration: once with the conditions and dispersant treatment (Treated Simulations) schedule observed at the DWH spill site and another simulation set is carried out for the whole duration without considering the dispersant treatment thorough out the spill (Untreated Simulations). The Treated Simulations results are saved in the folder named DWH_Hindcast_TR and the Untreated Simulation results are saved in the folder named 'DWH_Hindcast_UT'. Each hourly model results is saved as “BPM_DWH_M_D_H_Loc_No_disp.nc” where M- Month, D – Day, H – Hour, Loc - Location (No = 1 – Plume leaked at the kink before the riser cut off on 2010-06-03, Loc = 2 – Plume at the end of the fallen riser, Loc = 3 – Plume at the well head after the riser cut off on 2010-06-03) and if disp = TR, Plume is treated with dispersant and if disp = UT plume is not treated with dispersants. The model predictions at the plume termination for both Treated and Untreated Simulations are then provided to Connectivity Modeling System (CMS) developed at University of Miami to carry out the far field simulations. The model Output data that is provided the CMS model are saved in the folders named 'Input_CMS_Final' and saved in folders named 'DWH_Hindcast_TR' and 'DWH_Hindcast_UT' for treated and untreated plume simulations respectively. File naming is 'Input_CMS_M_D_H_Loc_No_disp_P.nc' where M, D, H, Loc, No, and disp are same as above and P stands for the phase of the particle and Liq- liquid and Gas - gas phase.
