Northern Wasatch Front Ozone Nonattainment Area

This page contains information about summertime ozone in the Northern Wasatch Front nonattainment area and an interactive emission inventory for the area. You can use thisInteractive Inventory to explore and learn about different emission sectors and sources (SCCs) within the Northern Wasatch Front, and where the emissions originate that drive the local ozone formation.What is summertime ozone?You’re probably familiar with

Particulate Chloride in the Urban Environment

The University of Utah will conduct a study intended to significantly reduce uncertainties regarding the temporal, spatial, and particle size distributions of particulate chloride. Through source apportionment, the study will also identify the dominant sources of this important halogen. These results will provide important emission inventory constraints for future air quality modeling efforts performed by UDAQ and others.

Impacts of the Great Salt Lake on Summer Ozone Concentrations Along the Wasatch Front

The University of Utah is conducting a study to determine the meteorological factors that contribute to elevated surface ozone near the Great Salt Lake. The core task for this project is to evaluate from ozone observations and meteorological observations and model analyses the timing of buildup in ozone in the southern Farmington Bay region and subsequent transport into Davis and Salt Lake counties. Completion of this task will provide resources that are likely to enhance operational air quality forecasting and provide critical information to initialize and verify air chemistry models used to identify approaches to meet federal air quality standards.

Development of Top-down Hydrocarbon Emission from Oil and Gas Production in the Uintah Basin

Utah State University and the University of Utah will use a method known as top-down emission estimation to refine volatile organic compound emissions from oil and gas production based on long-term surface level measurements of methane and hydrocarbons in the Uintah Basin. The objective of this project is to improve the Utah Division of Air Quality (UDAQ) bottom-up Uintah Basin Emission Inventory (UBEI), which is critical information for developing a regulatory model for UDAQ’s State Implementation Plan to attain the 8-hour federal ozone standard.

Development of a WRF-based Urban Canopy Model for the Greater Salt Lake City Area

Brigham Young University will conduct a two-year project that will utilize state-of-the-science meteorological modeling with land use descriptions of the Great Salt Lake area to characterize impacts of urban growth on local meteorological conditions. Model methodology and usage will be documented so air quality modelers can use existing or self-developed future results for additional urban growth and air pollutant assessments.

Assessing Wintertime Ozone Prediction Sensitivity to Photochemical Mechanism

Ramboll and the Utah State University – Bingham Research Center (BRC) will conduct a study to thoroughly investigate wintertime ozone prediction sensitivity in the Uinta Basin among two current photochemical mechanisms using a consistent modeling platform. Recent air quality modeling conducted by BRC using different modeling systems indicates that the Regional Atmospheric Chemistry Mechanism (RACM) produces much higher ozone concentrations than the Carbon Bond (CB) mechanisms. Ramboll and the BRC will comprehensively test and understand RACM2 performance in simulating wintertime ozone in the Uinta Basin relative to the CB version 6 (CB6) mechanism currently implemented in the CAMx air quality model used by the Utah Division of Air Quality.
