MOTTLES : Monitoring ozone injury for setting new critical levels


Project Description
  • 2016 - 2020
  • PM: Dr Pierre Sicard
    Project Manager

Tropospheric ozone is a harmful greenhouse gas, not only for human health, but also for forests. European standards to protect vegetation from this air pollutant are currently based on ozone concentration in the ambient air (AOT40), but the ozone effects on vegetation do not only depend on ozone concentrations, but also on the ozone uptake through the stomata. There is consensus in science that policy makers should implement new thresholds based on ozone dose, effectively, comes into the leaves. Hence, the project MOTTLES establishes a long-term monitoring strategy in three EU countries (Italy, Romania and France) in order to produce new scientifically-based critical levels for forest protection against ozone.
