1. Is there a correlation between wind speed and ozone concentration in NC? Erin Cooper

2. Purpose Surface ozone is harmful at extreme levels 0.075 ppm ozone = 100 AQI Ozone and weather both change constantly and affect us Air Quality Index Air quality ConditionsColors 0 to 50GoodGreen 51 to 100ModerateYellow 101 to 150Partially unhealthyOrange 151 to 200UnhealthyRed 201 to 300Very unhealthyPurple 301 to 500HazardousMaroon Polluted ozone can irritate and/or damage lungs, reduce lung function, or aggravate asthma or other chronic lung diseases

3. Hypothesis A region’s wind speed and ozone concentration will have a climatology correlation, but a very little correlation. If my hypothesis is correct, I can expect a negative correlation between wind speed and ozone concentration

4. Procedure 1.Chose DAQ stations near weather stations 2.Pull DAQ data from selected stations 3.Pull daily average wind speed data from weather stations 4.Organize data sets to correlate easier 5.Make correlation and graph data

5. Data Collections Southern Mountains Northern Mountains Northern Piedmont Central Piedmont Southern Piedmont Northern Coastal Plain Central Coastal Plain Southern Coastal Plain Wind Speed Data Station Asheville Regional Airport, Buncombe Boone- Watauga Hospital, Watauga Greensboro Airport, Guilford Siler City Airport, Chatham Douglas International Airport, Mecklenburg Highway Patrol Commercial Station, Martin Cunningham Research Station, Lenoir Horticultural Crops Res Station, New Hanover Air Quality Data Location Bent Creek, Buncombe Linville Falls, Avery Mendenhall, Guilford Pittsboro, Chatham Arrowood, Mecklenburg Jamesville, Martin Lenoir Community College, Lenoir Castle Hayne, New Hanover

14. The Southern Piedmont area had the most correlation, supporting my hypothesis The Northern Coastal Plain region had a positive correlation, disproving my hypothesis The Piedmont in general had the most correlation I also noticed that regions with major manufacturing cities had the highest correlation

15. Conclusion The piedmont region supported my hypothesis the most, having the most negative correlation Most regions had VERY little correlation The Northern Coastal Plain region completely rejected my hypothesis by having a positive correlation

16. Future Work More ways to figure out what affects Ozone concentration… Analyze data by a different time period Incorporate wind direction to see if that affects ozone concentrations
