Ozone Advisory issued by WYDEQ for March 10
For Upper Green River Basin in Sublette County
by Wyoming Department of Environmental Quality
March 9, 2008
(Upper Green River Basin, Wyo.) - The Air Quality Division (AQD) of Wyoming’s Department of Environmental Quality (DEQ), in conjunction with the Wyoming Department of Health (WDH), is issuing an ozone advisory for Monday, March 10, 2008, for the Upper Green River Basin, in Sublette County.
Ozone is an air pollutant that can cause respiratory health effects especially to children, the elderly and people with existing respiratory conditions. People in these sensitive groups should limit strenuous or extended outdoor activities, especially in the afternoon and evening. More information on ozone and the health effects of ozone are available at the Wyoming Department of Health website, http://www.health.wyo.gov.
Predictions of elevated ozone are based on evaluation of weather forecasts, and are therefore only as reliable as those forecasts. DEQ is conducting an intensive study of wintertime ozone formation in the Upper Green River Basin. Ozone appears to be elevated in the Basin when there are strong temperature inversions, low winds, snow cover, and bright sunlight.
Current information on ozone levels at the Air Quality Division’s monitoring stations at Daniel, Jonah, and Boulder can be found at www.wyvisnet.com.

2nd Editor's Note, Sunday, March 9, 5:00 PM: The Jonah webcam and data sensors came back online this afternoon. The Ozone and Particulate Matter sensors appear to be operational. The Nitrogen Dioxide NO2 sensor still does not appear to be showing data for the 24 Hour Rolling Average.
Editor's Note: The Jonah Air Quality webcam has been down since last week. Here is the explanation from Wyoming DEQ of what is happening with the equipment at that monitoring station:
“We began to have problems with the Jonah monitor earlier this week, and it has taken some time to trace the cause. Just today (Friday, March 7), I believe, our technical support contractor found that a software virus had affected the monitor's ability to communicate data to the system, so no data were being posted on the web site. Given the public concern about ozone conditions, we have made arrangements to replace the offending computer and the job should be finished late Sunday, March 9. I regret any inconvenience this may have caused your readers. To my knowledge, data on the web site for the Daniel and Boulder monitors has not been affected by this software problem.” - Dave Finley, Air Quality Division Administrator, Wyoming Department of Environmental Quality (DEQ)
