"Oil-affected area: Cumulative area with oil thickness above a certain threshold (start with zero)" |
Good idea, Susan. I’ve update the above list to reflect this differentiation in spill area calculations. I’ve also specified total mass of beached oil to be calculated as: mass = density(at last time step in .sro file) * 500 * 440 * thickness2D(in .nc) * 1e-6 This way, we avoid the need to incorporate changes in e3t and the calculation is more straightforward. |
I’m also updating the google spreadsheet that we have been using to sketch out comparisons and track progress on this front. See “Variable Comparisons” in this spreadsheet for more information. |
With spill spread and advection, need to calculate based on every half hour b/c last time step may not accurately reflect max distances |
Thickness_2D (time, grid_y, grid_x) - NEED TO EVALUATE
OilConcentration_2D (time, grid_y, grid_x) - If I recall correctly, the values in this are garbage |
@SusanEAllen and @campower, In[20] in this notebook from our OS2020 poster is the kind of graphic that I had in mind for "2D map of beaching time scales.” If we go this way, we will need to consider what to do with cases where beaching occurs at depth. My thinking here is to mask those locations out, though we may want to track the volume of "beaching at depth" vs. shoreline, in particular for the Bunker-C case, for issues of transparency and mass balance comparisons. |
Listed below is our current set of outputs.
1. Single point (scalar) values to calculate and/or put in model output “stats” file
2. Mappable values to calculate and add to output netcdf
3. Values already present in output netcdf
4. Values already present in output netcdf that I don’t yet trust and wouldn’t use w/o vetting
