Study Continues to Look at Ammonia’s Role in Utah’s Air Quality

This month, researchers finished gathering data for the Wasatch Front Ammonia and Chloride Observations (WaFACO) study. This study hopes to find the sources and role that ammonia plays in the formation of air pollution in Northern Utah.

Air Quality Researchers Hunt for PM2.5 Precursors

Researchers from DEQ, EPA, the University of Utah, Utah State University, and BYU joined forces for the Wasatch Front Ammonia and Chloride Observations (WaFACO) study. The study is looking for sources of ammonia on the Wasatch Front—a precursor to PM2.5.

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.

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, 2) particulate chloride spatial distributions, and 3) mobile real-time NH3 assessments.

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.
