  1. Determine spatial distributions, speciation and sources of Volatile Organic Compounds (VOCs) in the Wasatch Front region. Sources and VOC classes to investigate will include, but not be limited to the following.
    1. Volatile Chemical Products (VCPs) from sources such as household chemicals, consumer products, cooking, etc.
    2. Biogenic hydrocarbons (BVOCs), including their transport from vegetated mountain regions and canyons surrounding the urban areas.
    3. Petroleum refineries in North Salt Lake and Davis Counties.
    4. Pyrogenic VOCs during wildfire impacted periods.
  2. Determine spatial distributions, speciation and sources of nitrogen oxides (NOx = NO+NO2) and total reactive nitrogen, NOy. Areas of interest include the following.
    1. Mobile source emissions from vehicles
    2. Industrial sources, including mining operations associated with Bingham Copper
    3. Soil NOx from agricultural regions adjacent to the urban areas
  3. Determine spatial distributions, speciation and sources of halogens, including chlorine, bromine and potentially iodine compounds. Emphasis on the following topics.
    1. Emissions, transport and chemical transformation from the US Magnesium facility
    2. Aerosolization and heterogeneous chemistry associated with the Great Salt Lake and surrounding playas
  4. Characterize of important processes affecting the planetary boundary layer and transport of pollutants within and between basins within the region.
  5. Determine the sensitivity of local O3 formation to NOx and VOCs, and potentially halogens, based on modeling of the observations listed above.
  6. Determine of the influence of wildfire emissions on O3 formation in the urban areas of the Wasatch Front.
