Forests in Europe face significant changes in climate, which in interaction with air quality changes, may significantly affect forest productivity, stand composition and carbon sequestration in both vegetation and soils. Identified knowledge gaps and research needs include: (i) interaction between changes in air quality (trace gas concentrations), climate and other site factors on forest ecosystem response, (ii) significance of biotic processes in system response, (iii) tools for mechanistic and diagnostic understanding and upscaling, and (iv) the need for unifying modelling and empirical research for synthesis. This position paper highlights the above focuses, including the global dimension of air pollution as part of climate change and the need for knowledge transfer to enable reliable risk assessment. A new type of research site in forest ecosystems (“supersites”) will be conducive to addressing these gaps by enabling integration of experimentation and modelling within the soil-plant-atmosphere interface, as well as further model development.
► Research needs are identified for forests under climate change and air pollution.
► Abiotic–biotic interactions in response impede tree-ecosystem upscaling.
► Integration of empirical and modelling research is advocated.
► The concept of multi-scale investigations at novel “Supersites” is propagated.
► “Supersites” warrant mechanistic understanding of soil-plant-atmosphere interface.
