森林が光化学大気汚染に及ぼす影響:熱および汚染物質収支の同時計測 The in fluence of fbrest on the photochemical atmospheric pollution
Access this Article
The photochemical atmospheric pollution is a serious problem. Recently, it is said that biogenic hydrocarbons emitted from forests make some effects on the photochemical reactions, but it has not been confirmed because of the difficulty of measurement. We performed a field observation to estimate the balance of biogenic hydrocarbons, ozone and heat at a forest. The following results are obtained; 1) Ozone concentration over the forest is higher than that under the forest. 2) Biogenic hydrocarbons seems to be closely related to the ozone concentration through photochemical process. 3) The forest acts as a sink of ozone as a whole, but its magnitude is smaller than the ground surface.
