Abstract |
The results of field studies that measured the flux and deposition velocity of SO2 and O3 are reported. Three of the studies were over agricultural crops (pasture, corn, and soybean), and two were over forest (a deciduous forest and a mixed coniferous-deciduous forest). In all cases the deposition velocity for SO2 was higher than for O3. Diurnal cycles of SO2, deposition velocity were similar in shape, but not magnitude for all surfaces; however those for O3 showed some difference between forest sites where the peak was in the morning, and the agricultural sites where the peak occurred at midday. Seasonal cycles of SO2 were affected by deposition to surfaces when leaves weren't active, yet surface conductance is significant, but not the O3 where stomatal uptake is the primary pathway for deposition |
