Opens: November 4, 2019
Closes: January 17, 2020
The Utah Division of Air Quality (UDAQ) is seeking proposals for air quality research projects that help achieve UDAQ’s goals and priorities for the upcoming 2021 fiscal year (FY). See the following section for a description of 2021 FY goals and priorities. Coinciding with this announcement, UDAQ expects to award nearly $500,000 in State funding. The number of grants awarded is approximately 3 – 8, subject to the availability of funds, the quality of proposals received, and other applicable considerations. Funding is ongoing and UDAQ anticipates providing this opportunity on an annual basis.
Science for Solutions Research Grant Webinar
UDAQ hosted a short webinar on Thursday November 21, 2019 (4:30 – 5 PM) to go over key parts of the RFP and highlight differences from last year. View slides from the presentation (758 KB).
Fiscal Year 2021 Goals and Priorities
Research topics that UDAQ is seeking to fund are listed below. Research goals and priorities could change on a year-to-year basis. Only those proposals targeting one or more of the following topics will be considered for award.
Air Quality Modeling Improvements
Air quality models remain important tools for guiding policy makers in preparing State Implementation Plans to demonstrate compliance with federal air quality standards. Modeling enables UDAQ to demonstrate and quantify the effectiveness of future emission control strategies. Better characterization of the complex meteorological features associated with cold air pool as well as spring- and summer-time episodes is needed. Improved representation of the chemical mechanisms as well as physical processes relevant to ozone and PM2.5 photochemistry are also needed.
- Numerical representation of complex and missing chemical mechanisms
- Surface land use characterization and topography
- Urban canopy models and anthropogenic heat fluxes
- Albedo and snow cover representation
- Snow surface chemistry
- Cloud cover representation
- Nitric acid and organics deposition
- Exchange and transport processes
- Aerosol-radiation-cloud interactions
- Top-down turbulent erosion
Emissions Inventory Improvements
Recent studies along the Wasatch Front and Uinta Basin highlighted discrepancies between inventory estimates and measurements of several key precursors to the formation of ozone and PM2.5. These include carbonyls, hydrocarbons, alcohols, halogens, etc. Reconciling differences between inventory estimates and observations are needed for improved modeling of ozone and PM2.5. Information on the sources, spatial and temporal distribution of chemical precursors is also needed. This entails a better representation of:
- Source-specific organic compounds emission rate estimates
- Source-specific organic compounds speciation profiles
- Fugitive and missing emission sources (e.g. abandoned wells, gathering pipelines, pigging, water tank emissions)
- NOx emissions
- Methane emissions and ozone formation impacts
- Activity data
- Model of stochastic emissions (e.g. “super-emitters”, equipment malfunction)
- Halogens emission rate estimates
- Speciated volatile organic compounds
- Source-specific emission rate estimates for volatile organic compounds
- Emissions from cold-starting engines and catalytic technologies
Air Exchange Processes and Pollutants Mass Transport
Air mass exchanges are important meteorological processes affecting the transport of air pollutants. Air exchanges across the Great Salt Lake, different Utah valleys and canyons as well as between the polluted boundary layer and free troposphere affect the transport and mixing of key precursors to PM2.5 during winter. Regional meteorological processes also lead to long-range transport and stratospheric intrusion of ozone. A more detailed characterization of these processes and their impact on air pollutants chemistry and levels is needed.
- Lake-land interaction
- Canyon flows
- Inter-basin exchange
- Air pollutants mass transport estimates
- Oxidants exchange between cold air pool and free troposphere
- Long-range transport and stratospheric intrusion of ozone and its precursors
PM2.5 Formation and Precursor Gasses
To better inform air pollution control strategies in northern Utah, it is necessary to understand the complex chemical processes that contribute to secondary PM2.5 formation. Secondary PM2.5 accounts for over 50% of total PM2.5 during winter-time air pollution episodes. It is produced from complex atmospheric chemistry that involves several different gaseous compounds. UDAQ would like to better understand and quantify the sources of compounds contributing to winter-time air pollution along the Wasatch Front and Cache Valley. Information on their spatial, temporal, and vertical distribution as well as mass emission and photolysis rates are also needed. Compounds and parameters of interest include, but are not limited to:
- Volatile organic compounds
- Oxidized nitrogen compounds
- Atmospheric radicals
- Photolysis rates
PM2.5 Chemical Composition and Sources
Aerosol chloride plays an important role in winter-time PM2.5 formation. In the presence of excess ammonia, hydrochloric acid will partition to aerosol particles forming ammonium chloride. Particulate chloride can also contribute to the formation of nitryl chloride, which is a source of radicals for daytime photochemical production of ozone and nitrate. Emission sources of aerosol chloride are, however, unclear. Better identification of major chloride sources, including the Great Salt Lake, road salt, dry salt beds and industrial sources is needed. The contribution of organic aerosol sources to PM2.5 is also unclear.
- Particulate chloride sources
- Organic aerosol
Source Contributions to Summer-Time Ozone
The Wasatch Front often experiences exceedances of the national ambient air quality standard for ozone during the summer. Regulating locally-formed ozone to reach attainment is complicated by the fact that ozone has a mix of different sources. These include stratospheric transport, wildfires, biogenic emissions as well as international and US anthropogenic sources. To help establish control regulations, further research is needed to determine the contributions from these sources to summer-time surface ozone.
- Biogenic emissions
- Anthropogenic emissions
- International transport
- Stratospheric intrusion
- Lightning-induced NOx
