You can set deposition parameters in the "Pollutant, Deposition and Grids Setup" menu under the
main "Concentration Setup" menu. Click on "Specie 1" under Deposition. You will need to know what
the deposition parameters are for the specie you are trying to model. If you just want to set a
dry deposition velocity, just set it Vel(m/s) in the second row of numbers.
