Investigating Sources of Ammonia Uncertainty in Modeling the Salt lake City PM2.5 Nonattainment Area

This study will investigate the existing emission inventory of ammonia (NH3) sources and compare modeled NH3 concentrations to those observed during recent field studies in order to identify and correct missing NH3 sources. In addition to improving the inventory, this study will add new NH3 emission pathways to the photochemical model.

Understanding How Wood-Burning’s Contribution to Particulate Matter Concentrations Have Changed over Time

Wood burning contributes to fine particulate matter (PM2.5) pollution in the Wasatch Front, and reducing the use of wood burning during pollution episodes has been the focus of many policy decisions. This study looks at patterns of temperature, heat deficit, and day of the week along with markers of woodsmoke and mandatory no-burn days, to try and understand if public awareness and policy efforts have been effective in reducing wood burning during pollution events.
