Percentage of sites included in TOAR for which the trends (from 1995 through 2014) in TOAR exposure metrics (columns) were in the same direction (i.e., decreasing, increasing, or no significant change) compared to a set of metrics (rows), which included those in Lefohn et al. (2017). The mean and median metrics are included for comparative purposes.* DOI: https://doi.org/10.1525/elementa.279.t5
