High levels of daytime Cl-2 up to similar to 450 pptv were observed. The average diurnal Cl-2 mixing ratios showed a maximum around noon at pptv. ClNO2 exhibited a strong diurnal variation with early morning maxima reaching ppbv levels and afternoon minima sustained above 60 pptv. A moderate correlation (R-2 = 0.31) between Cl-2 and sulfur dioxide was observed, perhaps indicating a role for power plant emissions in the generation of the observed chlorine. We also observed a strong correlation (R-2 = 0.83) between daytime (10:00-20:00) Cl-2 and ClNO2, which implies that both of them were formed from a similar mechanism. In addition, Cl-2 production is likely associated with a photochemical mechanism as Cl-2 concentrations varied with ozone (O-3) levels. The impact of Cl-2 and ClNO2 as Cl atom sources is investigated using a photochemical box model. We estimated that the produced Cl atoms oxidized slightly more alkanes than OH radicals and enhanced the daily concentrations of peroxy radicals by 15% and the O-3 production rate by 19%.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000410255800019</style></accession-num><notes><style face="normal" font="default" size="100%">Fg4smTimes Cited:0Cited References Count:48</style></notes><auth-address><style face="normal" font="default" size="100%">Georgia Inst Technol, Sch Earth &amp; Atmospher Sci, Atlanta, GA 30332 USAUniv Colorado, Cooperat Inst Res Environm Sci, Boulder, CO 80309 USANOAA, Earth Syst Res Lab, Boulder, CO 80305 USAPeking Univ, Coll Environm Sci &amp; Engn, State Key Joint Lab Environm Simulat &amp; Pollut Con, Beijing 100871, Peoples R China</style></auth-address></record></records></xml>
