Fires are a major source of gaseous and particulate pollutant, including black carbon (BC). In combination with organic carbon (OC), nitrogen oxides (NOx), and volatile organic compounds (VOCs), BC from fire emissions causes air quality degradation. BC is also increasingly…

Studies project that a warming climate will likely increase wildfire activity in many areas (Westerling and others 2002; Flannigan and others 2005, 2009; Littell and others 2009). These analyses are often of aggregate statistics like annual area burned, which are insufficient…
