The air above a small forest in the Campine region of Flanders, Belgium, was the subject of this decade-long study to understand ozone flux patterns. The data, which was presented at the COST International Conference on Ozone, Climate Change and Forests in June last year, shows that rain had a significant effect on the deposition of O3 in the tree canopy.
R. Ceulemans and colleagues found that during the day a dry canopy was the best sink for ozone, whereas at night the converse was true – a wet canopy showed the highest ozone deposition. Read the article for their speculations about non-stomatal deposition:
