Model sensitivity was tested with regard to all pollutant parameters
in its input (see SI for more details): solubility enhancement
factor due to aqueous dissociation, reactivity factor of
depositing gas with surface, resistance to dissolution or reaction in
mesophyll, pollutant air diffusivity, and Henry's Law coefficient.
Out of these parameters, pollutant air diffusivity was found to be
the most influential since it is employed in the removal equations in
the CALPUFF model.
