Concentration / Setup Menu / Deposition Definitions

This section is used to define the deposition parameters for emitted pollutants. The number of deposition definitions must correspond with the number of pollutants released. There is a one-to-one correspondence. There are 5 entries in the CONTROL file for each defined pollutant. The lines 27(1) through 31(5) correspond with each of the menu items shown in the illustration below. The radio-buttons along the top can be used to set default deposition parameters, which can then be edited as required in the text entry section. The reset button sets all deposition parameters back to zero.

26 - Number of pollutants depositing

27(1)- Particle: Diameter (µm), Density (g/cc), and Shape

28(2)- Deposition velocity (m/s), Pollutant molecular weight (Gram/Mole), Surface Reactivity Ratio, Diffusivity Ratio, Effective Henry's Constant

29(3)- Wet Removal: Actual Henry's constant, In-cloud (L/L), Below-cloud (1/s)

30(4)- Radioactive decay half-life (days)

31(5)- Pollutant Resuspension (1/m)
