INPUT GROUP: 8 -- Size parameters for dry deposition of particles<br />

--------------<br />

For SINGLE SPECIES, the mean <strong>and</strong> st<strong>and</strong>ard deviation are used to<br />

compute a deposition velocity for NINT (see group 9) size-ranges,<br />

<strong>and</strong> these are then averaged to obtain a mean deposition velocity.<br />

For GROUPED SPECIES, the size distribution should be explicitly<br />

specified (by the 'species' in the group), <strong>and</strong> the st<strong>and</strong>ard deviation<br />

for each should be entered as 0. The model will then use the<br />

deposition velocity for the stated mean diameter.<br />
