Current Research: Modelling BVOC Emissions and their Impact

The interactions between vegetation, climate, and trace gas concentrations in the troposphere are numerous and complex. Increasing levels of carbon dioxide mean that plant growth may be stimulated, as many are limited by carbon dioxide levels. However, the corresponding increase in temperatures mean that conditions may get too hot for some species, and soil moisture levels may fall, both of which act to reduce growth.
Vegetation is known to emit a wide range of volatile organic compounds (BVOCs), of which the most important are isoprene and monoterpenes. These BVOCs are highly reactive, and play an important role in controlling the surface concentrations of ozone. Their emissions may increase in the future, owing to the warmer temperatures. They are also an important source of aerosols, which in turn control cloud properties and the radiation budget at the surface. Increasing carbon dioxide levels act to reduce the size of stomata on the surface of leaves, which reduces the uptake of toxic gases such as ozone by vegetation. Ozone is know to damage vegetation and rising ozone levels may reach dangerous levels in the future, reducing yields from crops, and the quality of the crop.
The interactions between vegetation, rising carbon dioxide levels, and ozone levels will be studied using a fully dynamic earth system model, allowing the key feedbacks between vegetation, atmospheric chemistry and climate to be identified and quantified.

This project (ESRII) contributes to science objective 5 (Quantify impacts of climate change on terrestrial and oceanic biogenic emissions of aerosols and chemically active gases, and their effects on tropospheric chemistry).
