- Problem #1 - All the previous dust simulations were done assuming no gravitational settling. Rerun the last dust simulation, the one with the corrected emission factors, with deposition and evaluate changes.
- Hint - Assume a particle density of 4.0 g/cc with a diameter of 2.5 µm and a shape factor of 1.0
- Solution - The scatter diagram and statistical results with deposition should be compared with the previous no deposition scatter and statistical results.
- Problem #2 - Using the output from problem #1, display the concentration contours with the sampling data and county boundaries.
- Hint - From the concentration display menu optimize the map scale by forcing the map center and radius, define a map background with county boundaries, adjust the contour intervals to clarify the graphic, and select the measured data file.
- Solution - These options result in this graphic, although many other combinations will also produce satisfactory results.
