Atmospheric Chemistry

Clouds above the Earth

The Atmospheric Chemistry Research Group (ACRG) focus on the atmospheric monitoring of important environmental gases, alongside the interpretation of this data. Long-term in situ measurements generate important atmospheric composition data for modelling of gases for interpretation and interpolation of factors such as European source strengths and Northern Hemispheric atmospheric baselines.

There is a particular interest in establishing trends within global and regional networks operating similar instrumentation. Such networks allow for integration of potential source regions of environmentally important gases. The networks we are involved in include the Advanced Global Atmospheric Gas Experiment (AGAGE) and the System for Observation of Greenhouse gases in Europe (SOGE). The focus for both programs is for trend detection in halocarbon species, particularly CFCs and their replacements (HCFCs and HFCs), and halocarbons.
