Outline of Final Research Achievements

In order to better understand the mechanism of gas and particulate reactive nitrogen deposition to forests, we carried out dry deposition measurements in a temperate mixed forest, a cool temperate larch forest and a tropical dry deciduous forest.
These measurements clearly showed the difference in dry deposition process between nitrate and sulfate in PM2.5. The concentration gradients of nitrate from over to under the canopy were significantly higher than those of sulfate, during leafy period in all of the forests. Moreover deposition velocities of nitrate greater than theoretical were observed.
The analyses of numerical models showed that the equilibrium shift of NH4NO3 into the gas phase during the daytime hot canopy can decrease nitrate concentration, and the volatilized HNO3 was immediately removed by the canopy. Therefore, the equilibrium shift enhanced the dry deposition of nitrogen within nitrate.

Academic Significance and Societal Importance of the Research Achievements

ガス・粒子状反応性窒素が森林へ沈着するメカニズムにおいて、未だに解明されていない半揮発性のNH4NO3粒子の乾性沈着を理解するために、アジアでは初となる本格的な乾性沈着観測を温帯混合林(東京)、冷温帯カラマツ林(北海道)、熱帯乾燥落葉樹林(タイ)において実施するとともに、数値モデルを使った高度な解析を行った。
観測を実施したすべての森林において、森林キャノピー内のNH4NO3粒子濃度が減少していることが確認され、数値モデル解析により、日中温められた樹冠が粒子をガス化させ、その沈着を促進させていることが明らかとなった。これにより、現在の乾性沈着モデルの誤差要因の一つが見出された。
