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).
