Abstract
On theoretical grounds it is expected that particulate sulfate will deposit more slowly than SO2. While micrometeorological measurements of the deposition velocity of SO2 are relatively common, similar simultaneous measurements for sulfate have not been reported. To measure their relative deposition velocities, as well as that of NOx, a field study was conducted over ungrazed grass in central Ohio in September 1979. Daytime deposition velocities for SO2 were typically 0.8 cm/sec, while for sulfate typical daytime values were 0.4 cm/sec, which is noticably higher than commonly assumed values.
