  1. Research Results: Impact of Sea Breeze on Ozone Edgewood, MD Joel Maruschak Victoria Faranca

  2. Daytime / Overnight Pattern Green: Values Below 10 Red: Values above 70 Times in Local Standard Time

  3. Impressive Days

  4. July 02, 2011 Worst day of the month in terms of ozone concentrations.  Highest daytime mean Highest max ozone Highest overall average! Clear skies with no clouds throughout the entire day Warm temperatures BL mixing Strong PM wind shift with increasing wind speed. Rapid increase in ozone Evidence of Sea Breeze

  5. July 2, 2011 – Highest Ozone Maximum and Highest Average, Highest Difference Between Overnight and Daytime Means

  6. July 03, 2011 Maximum Overnight Mean Mostly cloudy Evidence of sea breeze Northwest wind brought higher concentrations of ozone from south central PA into the area. Increasing ozone concentrations overnight 46 ppb for overnight mean

  7. July 3, 2011 – Maximum Overnight Mean

  8. July 08, 2011 Overall lowest average ozone Cloudy skies!! Clearest skies during overnight hours Large wind shift Not well mixed Increasing wind speeds throughout the day Evidence of Sea Breeze Secondary drop in ozone likely due to heavy rain in afternoon

  9. July 8, 2011 – Overall Lowest Average Ozone

  10. July 09, 2011 Lowest overnight mean of the month Overcast during the evening and clear during the AM hours. Clouds leading to minimal mixing of BL. Although this day was sunny and favorable for Ozone production, the strong daytime winds were blowing ozone out to sea throughout the day. Thus no evidence of sea breeze! ~14ppb for overnight average

  11. July 9, 2011 – Lowest Overnight Mean

  12. July 14, 2011 Lowest daytime mean of the month Likely due to missing data! Very clear skies This could have been an average dayor potentially even a high ozone day.

  13. July 14, 2011 – Lowest Daytime Mean

  14. July 22, 2011 Overall highest max of the month Clear skies during the daytime Moderate mixing HAZE Strong winds blowing dirty air into area during the day causing ozone to peak during the day. Ozone likes warm temperatures Over 100°F Max of 118 ppb

  15. July 22, 2011 – Highest Ozone Reading
