Lead is a toxic metal that was once used regularly in motor fuel, paint, ceramics, glassware, and other consumer products. The phase-out of leaded gasoline significantly reduced vehicle emissions and lead levels in the environment, but it is still used in some aviation fuels and used or produced in a variety of industrial processes. The …Read More

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.
