TL;DR: The present work may help the set-up of further long-term forest monitoring sites dedicated to O3 assessment in forests, especially because flux-based assessments are recommended as part of monitoring air pollution impacts on ecosystems in the revised EU National Emissions Ceilings Directive.

TL;DR: State-of-the-art simulations models were used to evaluate the utility of C-, L- and P-band synthetic aperture radar (SAR) sensors within an integrated Earth-Observation monitoring system for beech, oak and coniferous forests in Romania, showing differentiated sensitivity to vegetation water content, leaf area index, and forest disturbance depending on SAR wavelength and forest structure.

TL;DR: Evaluation of the individual process-based model HETEROFOR showed that it predicts individual tree radial growth and height increment reasonably well under different growing conditions when evaluated on independent sites, giving the forester the possibility to act on the productivity of broadleaved forests and prepare them for possible adverse effects of climate change by reinforcing their resilience.

TL;DR: Ozone concentration and AOT40 under Romanian conditions were more important than meteorological parameters in affecting crown defoliation, and POD0 never exceeded the critical level suggested by previous literature for forest protection, and thus was not important.
