摘要

Transport of biogenic species and the subsequent influence on photochemistry in thernatmospheric boundary layer is addressed. The dynamical influence imposed by thernpresence of a plant canopy is shown to influence the mixing process. Compared to anrnassumed well-mixed situation, distributed sources through the canopy layers tend to slowrnreaction rates above the canopy and enhance reaction rates within the sub-canopy layersrnrelative to a case without a canopy. Large-scale horizontally heterogeneous emissionsrnare shown to dramatically reduce reaction rates by segregating the species. Compared tornsimple chemistry with horizontally homogeneous emissions, more complete chemistryrndiminishes the effect of transport on reaction rates by enhanced in situ production ofrnreactants.
