Impacts of wildfires and mobile emissions on ozone concentrations in the Treasure Valley, Idaho
Abstract
The Treasure Valley in Idaho experienced significant air quality problems with PM10 and CO especially in the winter, because of wood smoke, emissions from unregulated older vehicles, and road dust during the last decade. The mixing ratios of O3 and its precursors were analyzed conjointly with weather maps, trajectories, and wildfire data to examine the impact of wildfire emissions on high O3 events in Treasure Valley. A set of nine high O3 events were identified by means of weather conditions, trajectories of air masses, and wildfires events. The characteristics of these events were compared against those determined for typical O3 events. Four of the high O3 events were affected by wildland fires in southern Idaho, northern Nevada, and California. The remaining four high ozone events showed slightly lower 03, VOC, and PM2.5 but elevated N0. This is an abstract of a paper presented at the 101st AWMA Annual Conference and Exhibition (Portland, OR 6/24-27/2008).
