Utah Dust Research
Back to Utah Dust Home What and why are we measuring? Air quality concerns related to dust depend on the size and chemistry of the particles. We focus on particulate matter (PM), which are tiny pieces of dust in the air and the metals contained in the dust. Inhalable and respirable dust Airborne dust mostly…

Role of Atmospheric Boundary Layer Dynamics on Summertime Air Pollution in the North Wasatch Front
The project will analyze air quality and meteorology data collected during the 2024 Utah Summer Ozone Study (USOS) to investigate the role of atmospheric boundary layer dynamics in summertime ozone in the Salt Lake City region. One main task is to conduct a comprehensive analysis of boundary layer dynamics using airborne Doppler lidar measurements and…

Advancing Biogenic VOC Emissions Modeling for the Wasatch Front: Emission Factors, Speciation, and Stress-Induced Emissions
The project aims to improve Biogenic Volatile Organic Compound (BVOC) Emissions Modeling for the Wasatch Front, which is essential for developing effective air pollution control strategies for the region’s ozone nonattainment. The scope of work includes synthesizing an updated BVOC emission factor database, enhancing rural landcover inputs for the MEGAN model using datasets like LANDFIRE…

Comprehensive Google Earth Engine and Satellite Data Analysis Tools to Assess the Impacts of VOC-NOx Sensitivity, Smoke, Heat, Drought, and Plant Stress on Ozone Concentrations in Utah and the Northern Wasatch Front
The goal of this study is to assess summertime ozone sensitivity to volatile organic compounds (VOCs) and oxides of nitrogen (NOx), as well as the impact of changing conditions like wildfire smoke and drought, on ozone concentrations in the Northern Wasatch Front. The core methodology will focus on the Formaldehyde-Nitrogen Ratio (FNR), derived from TROPOMI…

Assessing Community Exposure to Ambient Particulate Matter from the Great Salt Lake
The shrinking Great Salt Lake exposes over 750 square miles of potentially metal-contaminated lakebed dust, and this project aims to quantify community exposure to the resulting airborne PM10 in Wasatch Front communities. The methodology involves a combination of continuous PM monitoring, analysis of particle size, oxidative potential, and metal/organic carbon composition. These measurements will be…
