Dry Depositi<strong>on</strong><br />
‣ Complex process<br />
‣ Resistances: Aerodynamic, boundary layer, and<br />
surface<br />
‣ Surface resistance functi<strong>on</strong> of compositi<strong>on</strong>,<br />
wetness, plant cover, and N-species<br />
‣ Depositi<strong>on</strong> directly to surfaces and/or through<br />
stomata<br />
‣ Up to 45 kg-N ha -1 yr -1 in San Bernardino Mtns,<br />
20-30 kg-N ha -1 yr -1 in Riverside<br />
‣ Flux = Dep Velocity X C<strong>on</strong>centrati<strong>on</strong>
