Science Buddies: "Ask an Expert"

My project was what area in NYC had the highest level of ozone. We observed the highest level in Central Park, and the other areas were near streets and airports. My questions is why the area with most trees and few streets had the highest level of ozone?
Thank you!

I looked into your question. My basic research suggests the opposite should be true. However, to understand more of what may be going on, could you provide more info about your test Proceedures? What time of day did you take readings? Did you take readings at the different locations on the same day? What equipment did you use? How many readings at each location did you take? Did you repeat the experiment two or more times? What was the environment like (windy, rainy, calm, etc...)? Any other info you can provide.

Thanks, post back and we'll see if we can't troubleshoot your experiment.
