The monthly measured concentration of NO₃^- was found to be greater than that of SO₄^2-. The average dry deposition flux of NO₃^-was found to be greater than that of SO₄². The average deposition velocities of sulfate were evaluated to be 0.30 cm s^-1 during the day and 0.22 cm s^-1 at night, while the highest deposition velocities of nitrate were 0.93 cm s^-1 during the day and 0.54 cm s^-1 at night. The deposition velocities of aerosols (SO₄^2- and NO₃^-), calculated by using the resistance model, were found to be 0.49 cm s^-1 during the day and 0.29 cm s^-1 at night.}, doi={10.12691/jap-1-1-1} publisher={Science and Education Publishing} }
