Category: Model Improvements Current & Ongoing Studies
Air quality models are used to predict atmospheric conditions in the future. They are based on meteorological conditions, chemistry mechanisms, and inventories of reported emissions. Models are tested for correctness by comparing their results to observed atmospheric characteristics, such as PM2.5 concentrations during high pollution periods in the past. The following studies show various ways in which models are being improved to better reflect observations of the atmosphere in Utah.
Current & Ongoing Studies
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.

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.
