Christopher Holmes and Jason Ducker (IMAGE) Florida State University Caption From left, Christopher Holmes, the Werner A. and Shirley B. Baum assistant professor of meteorology in the Department of Earth, Ocean, and Atmospheric Science at Florida State University, and Jason Ducker, a postdoctoral researcher. Their research compared levels of atmospheric ozone to the amount of ozone plants took in through pores on their leaves at more than 30 sites over 10 years. They found that environmental factors have more impact on the ozone dose the plants received than the amount of ozone in the atmosphere.
