    Investigating Dry Deposition of Ozone to Vegetation by Silva, Sam James, Heald, Colette L.

    Published 2018
    “…When correctly accounting for differences in land class between the observations and model, these biases improve, most substantially over the grasses and shrubs land class. These biases do not impact the global ozone burden substantially; however, they do lead to local absolute changes of up to 4 ppbv and relative changes of 15% in summer surface concentrations. …”
