抄録

It was reported that, above a red pine forest in Nagano, sulfate aerosol (SO₄^2- ) was not only deposited to the red pine forest but also was emitted, and this would be related to terpenes emission (Suzuki et al. 2001). In this research, concentration, flux and deposition velocity of SO₄^2- were observed above red pine forests in Nagano and in Yamanashi where terpenes are emitted, and above a paddy rice field in Tokyo where terpenes are not emitted. <br>　The concentration of SO₄^2- were 2 - 124 nmol/m³ above the red pine forests in Nagano and Yamanashi and 9　- 40 nmol/m³ above the paddy rice field. The fluxes of SO₄^2- (FSO₄^2-) ranged from -8 to 8 nmol/(m² s) above red pine forests in Nagano and Yamanashi, and ranged from -0.05 to 0.4 nmol/(m2 s) above the paddy rice field. The difference in concentration of SO₄^2- and FSO₄^2- between the red pine forests and the paddy rice field would be related to terpenes emission from red pine forests. The deposition velocities of SO₄^2- (KSO₄^2-) ranged from -9 to 7 cm/s above the red pine forests in Nagano and Yamanashi, and ranged from -0.6 to 1.5 cm/s above the paddy rice field. The difference in KSO₄^2- between the red pine forests and the paddy rice field is not clear. The concentrations of SO₄^2- had a positive relation to O₃ concentrations, and FSO₄^2- and KSO₄^2- showed no clear relation to all measured environmental factors.
