FORCAsT-gs: Importance of stomatal conductance parameterisation to estimated ozone deposition velocity

Abstract

Medlyn coupled stomatal conductance-photosynthesis model best reproduces observed plant productivity (GPP) across various ecosystems • Modelled GPP and stomatal conductance across forest ecosystems differ by up to a factor of 2 between different model configurations • Ozone deposition rates could vary by ~13% depending on stomatal conductance model used with implications for estimated tropospheric ozone
