Abstract
|
|
|
This study analyzes the characteristics of ozone weekend effect(OWE) in Busan. O3 concentration on Sunday was over
10% higher than that on weekdays in all areas except for Kwangbokdong, Taejongdae, and Joadong. Such a difference was higher in the industrial area than in the residential area. O3 generation was facilitated by the decrease in NOx emission on Sunday in VOC-limited regime where the VOC/NOx ratio is low. Low NO concentration in the Sunday morning decreased inhibition of O3. NO-O3 crossover time on Sunday was shorter than that on weekdays which in turn extended the accumulated duration of O3. Future studies can include whether the entire Busan is VOCS-limited or the coastal area is VOCS-limited while the inland area is NOX-limited.
