Date and Location

Workshop date and time: 27 March 2019, 11:00AM to 5:00PM (lunch provided)
Location: Rooms 307-309, Eccles Conference Center, Utah State University, Logan, Utah (41.7419, -111.8109)
                Park at the Big Blue Terrace parking garage (41.7442, -111.8126)

**The workshop is co-located with and will occur one day prior to the Air Quality: Science for Solutions research conference


To register, please fill out the form, click on the "Pay Now" button, and enter your payment information.  The registration fee is $15
The registration fee will be used to pay for facilities and food.


  1. Share technical information about 3-D photochemical models of wintertime air quality so those developing these models can avoid duplicated effort and have access to the latest model improvements and techniques, and
  2. Connect researchers with regulators and industry to ensure that wintertime air quality models developed are relevant to all stakeholder needs.
The workshop will be focused on the technical aspects of air quality models and on measurements and other information that are used to inform or evaluate these models.  The workshop will emphasize modeling in regions with wintertime ozone, but those with experience in other regions with similar characteristics (e.g., wintertime temperature inversions in areas with complex terrain, oil and gas-related emissions that impact air quality, etc.) are also encouraged to attend.


We welcome anyone who researches wintertime air quality, as well as anyone whose work is impacted by wintertime air quality, to attend.  The workshop will be technical in nature.  

Currently, registrants include representatives from:
  • Utah State University
  • University of Utah
  • University of Wyoming
  • Utah Division of Air Quality
  • Wyoming Department of Environmental Quality
  • Bureau of Land Management
  • Environmental Protection Agency
  • Western Energy Alliance
  • Oil and gas companies
  • Environmental consulting companies
  • Breathe Utah


  • 11:00: Each entity in attendance gives a brief introduction (powerpoint optional) of their organization and its involvement in winter air quality modeling (5-10 min for each presentation).
  • 12:30: Lunch
  • 12:45: Lunchtime group discussion: Regulatory and industry wintertime air quality modeling perspective and needs
  • 1:30: Breakouts by topic into groups.  Attendees will self-select a group to participate in. 
    1. Topics include:
      1. Meteorology and boundary conditions
      2. Emissions, including source apportionment
      3. Air and surface chemistry, including process analysis
    2. Each group discusses:
      1. What is being or has recently been done to improve this aspect of modeling?
      2. What hurdles or gaps remain that need to be addressed?
      3. What options exist for addressing these hurdles?
    3. Each group prepares a quick and dirty powerpoint to share their findings with all attendees.
  • 3:00: Snacks
  • 3:15: Presentations by each group to share the result of their discussion (15 min + 5 min for questions for each presentation).
  • 4:15: Group discussion: Are the groups’ assessments and plans consistent with regulatory and industry modeling needs?  What will or won’t work?
  • 4:45: Group assessment of the workshop.
    1. Was it useful?
    2. Is another one needed in the future?
      1. If so, what could be changed to improve future workshops?
      2. If so, how often should the workshop be held?
      3. If not, is there another means by which we can accomplish the workshop objectives?
  • 5:00: Adjourn
  • 6:30: Dinner together for those who can (group reservation, but attendees pay their own bill)

  • After the workshop: each group will turn their presentation into a short (2-4 page) report of their group’s findings. These reports will be posted on the workshop website.
