Upper Green Winter Ozone Study Upper Green Winter Ozone Study (UGWOS)(UGWOS)
• Upper Green River Wintertime Ozone Study – UGWOS 2007
• Lack of snow and no elevated ozone episodes
• Learned enough for planning future years
• UGWOS 2008
• Significant elevated ozone observed
• Documented spatial scale of problem and developed conceptual model
• UGWOS 2009, 2010
• Focused on additional chemistry
• Improved mesonet monitoring coverage and communications
