Elizabeth Wiggins received a best student poster award for her work on “Environmental Controls on Wildfire Emission Factors in Alaska during 2015.” Liz was able to show that emission factors for carbon monoxide and methane from boreal forest fires may be higher than previous estimates because of significant emissions during night time periods with smoldering combustion. In her analysis, Wiggins combined continuous time series measurements of CO2, CO, and CH4 from a tall tower in Alaska with an atmospheric model. The use of the atmospheric model allowed her to estimate the back trajectory and origin of trace gas signals measured at the tower. Congratulations to Liz!
