During non-pollution period,SO_4~(2-) was mainly from aged air mass with high sulfur oxidation ratio which was promoted by O_3 during long range transportation.During pollution period,SO_4~(2-) was mainly from original source with lower sulfur oxidation ratio which had no obvious correlation with O_3.Except wind speed,there were no significant correlations bwteen meterological facotrs and sulfate and between meteorological factors and sulfur oxidation ratio during observation. %K SO42-
