Improving WRF/CMAQ Model Performance using Satellite Data Assimilation Technique for the Uintah Basin
This study will test if satellite observations of vegetation and land use can be used to improve photochemical model performance in the Uintah basin. An improved model will help inform emission reduction strategies and regulatory action.

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.

The Red Butte Canyon Ozone Network:
Leveraging Existing Infrastructure to Probe Background Concentrations, Canyon Flows, and Stratospheric Oxidant Exchange
This study will deploy a number of ozone sensors at different distances up Red Butte Canyon to better understand natural gradients in ozone and how phenomena like large thunderstorms and valley drainage flows contribute to ozone concentrations in the Salt Lake Valley.

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.
