The Influence of Synoptic Weather Conditions on Weekday-weekend Effect of Extreme Ground-level Ozone Events in the Toronto area
Ground-level ozone (O3) is a familiar pollutant because it is associated with summer haze and smog alerts. The 2000-2008 weekday-weekend variations of ozone concentration were examined in relation to the Toronto weather conditions. The goal of this work is twofold: (1) To determine whether extrem...
