The group focuses on the evaluation of tropospheric ozone effects in terms of ozone visible symptoms (see ICP Forests Manual Part VIII). We investigating temporal and spatial trends of injury occurrence in relation to ambient ozone concentrations. The analyses of Level II data from the last 16 years are embedded in a broader evaluation and publication concept on ozone risk assessment across Europe.…See More

The group focuses on the evaluation of tropospheric ozone exposures from passive samplers and real-time monitors (see ICP Forests Manual part XV). We aim at investigating temporal and spatial trends of ozone concentrations, based on Level II data from the last 10 years. The analyses are embedded in a broader evaluation and publication concept on ozone risk assessment across Europe. For detailed info, see…See More

Predicting Ozone Fluxes, Impacts, and Critical Levels on European ForestsTropospheric ozone (O3) is considered to be more damaging to vegetation than any other air pollutant. Public concerns, evidence from research, and increasing scientific knowledge are all driving widespread discussions on ozone risk assessment and dose-response relationships for European forests. In particular, there is high uncertainty concerning the effect of ozone on individual tree diameter increment and forest growth.…See More
