The Red Butte Canyon Air Mass Exchange and Pollution Transport Study
The University of Utah will make measurements of vertical wind and aerosol profiles, as well as ozone and fine particulate matter (PM2.5) concentrations at the mouth of Red Butte Canyon in order to better understand air exchange in the Salt Lake Valley during wintertime PM2.5 events. Principal Investigators: Sebastian W. Hoch, Erik T. Crosman (UU)…

The Red Butte Canyon Ozone Network:
Leveraging Existing Infrastructure to Probe Background Concentrations, Canyon Flows, and Stratospheric Oxidant ExchangeThis 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. Principal Investigators: Logan Mitchell, Ryan Bares, David Eiriksson (UU) Funded by Science for…

Jordan Narrows Gap Ammonia Transport Study
This study will provide key meteorological support for the chemistry observations taken during the upcoming 2018--2019 winter season that are focused on the ammonia transport and air mass exchange between the Salt Lake and Utah Valleys. Principal Investigators: Sebastian W. Hoch, Erik Crosman (UU) Funded by Science for Solutions Grant: $19,510

Wasatch Front Ammonia and Chloride Observations (WaFACO)
The objective of this study is to define the spatio-temporal behavior of atmospheric ammonia (NH3) and hydrochloric acid (HCl) along the Wasatch Front across both summer and winter seasons. This objective will be accomplished through three tasks developed in consultation with UDAQ and the U.S. EPA. These tasks include 1) networked NH3 and HCl observations,…

Aethalometer Study for Estimating Compliance
with Wood-burning BanThe University of Utah Department of Chemical Engineering will collaborate with UDAQ to estimate the contributions of wood burning to wintertime PM2.5 levels using aethalometer data from four locations and from mobile aethalometer measurements. The goal of this study is to identify and understand levels of wood burning and compliance with wood-burning restrictions during the…

Composition of Volatile Organic Compound Emissions From Oil and Gas Wells in the Uinta Basin
The Utah Division of Air Quality (UDAQ) is leading a new effort to improve estimates of the speciation of organic compound emissions from Uinta Basin oil and gas wells. Utah State University (USU) will work with UDAQ to collect and analyze pressurized gas and liquid samples from oil and gas well separators, as well as…

Bountiful City Dichloromethane and Formaldehyde Source Apportionment Study
A source apportionment campaign, with an emphasis on determining the source of dichloromethane in Bountiful City, will be conducted between December 2018 and January 2019. Supporting measurements of PM2.5 concentration and composition will be provided as part of this effort. Principal Investigators: Kerry Kelly (UU), Jaron Hansen (BYU) Funded by Science for Solutions Grant: $80,067

Ammonia Emission Assessment from Diesel and Gasoline Engines under Utah Specific Conditions
To better understand the contribution of automobiles to Utah ammonia emissions, tailpipe ammonia (NH3) measurements will be taken in laboratory and on-road settings for an array of diesel and gasoline vehicles representative of Utah’s vehicle fleet. Principal Investigators: Randal S. Martin (USU), Joe Thomas (UDAQ), John Sohl (WSU) Funded for: $59,958
