Ozone Pollution and Climate Change Exposure Facility (Aber Solardomes)

The purpose of the Aber experimental exposure facility is to determine the impact of ozone on vegetation such as crops, grassland, heath and small trees. Ground-level ozone is not only an air pollutant, it is also a greenhouse gas, contributing to global warming. Background ozone concentrations are rising and average levels are now above thresholds for adverse effects on vegetation (e.g. reduced growth, leaf damage) in many areas of the UK. The Aber facility enables researchers to study the interactive effects of air pollutants and a changing climate (such as warming, drought and flooding) and to establish critical thresholds and tipping points for ozone effects on vegetation.
