Evaluation of simulated ozone effects in forest ecosystems against biomass damage estimates from fumigation experiments

This research paper evaluates the accuracy of four previously published ozone damage functions used in terrestrial biosphere models by testing them against data from 23 ozone filtration and fumigation experiments involving young European tree species. The study finds that none of the existing functions could accurately simulate observed biomass reductions, but that developing linear, plant-functional-type-specific dose-response relationships through re-parameterisation leads to accurate simulations.

• An evaluation of four previously published ozone damage functions using the O-CN biosphere model revealed that none of them could accurately reproduce observed ozone-induced biomass reductions, resulting instead in significant over- or underestimations of the ozone effect.
• The study utilized data from 23 ozone filtration and fumigation experiments conducted with young European tree species across various climatic sites in Europe to test the leaf-level photosynthetic response functions (specifically targeting net photosynthesis or the maximum carboxylation capacity of Rubisco (Vcmax)).
• By re-parameterising the photosynthetically based injury functions, the authors created linear, plant-functional-type-specific dose-response relationships that achieved good agreement and accurate simulations of observed whole-tree biomass responses across the 23 experiments.
