  • Problem #1 - The original Sagebrush simulation showed a slight under-prediction for the highest concentrations, those on the arc located nearest to the source. Is this related to one of the model configuration options?

  • Hint - The plume near the source is much narrower than the width of the concentration grid cell. Edit and run the batch file conc_local.bat.

  • Solution - Scatter Diagram and Statistical Results.


  • Problem #2 - Recompute problem #1, but this time, in addition, reduce the vertical depth of the concentration grid from 25 to 10 m.

  • Hint - Edit and run the batch file conc_local.bat.

  • Solution - Scatter Diagram and Statistical Results.


  • Problem #3 - Recompute problem #2, but this time, use the STILT mixing options idsp and wvert.

  • Hint - Edit and run the batch file conc_local.bat.

  • Solution - Scatter Diagram and Statistical Results.
