Keywords:forest, atmosphere, nitrogen oxides, ozone, VOC, vertical profile

We measured vertical profiles of nitrogen oxide, NO, nitrogen dioxides, NO2, ozone, O3, and VOC in the atmosphere in Fujiyoshida and Hokuroku forest observation sites at the foot of Mt. Fuji in summer 2012. The concentration of ozone increased gradually with the height, but the concentrations of NO and NO2 did not changed obviously. VOCs showed characteristic vertical profiles. We calculated O3 fluxes at parts of in and under the canopy, and around the surface layer as -2.6 ± 3.2 nmol m-2 s-1, 0.2 ± 2.9 nmol m-2 s-1, -8.7 ± 5.2 nmol m-2 s-1, respectively.
