Final Activity Report Summary - BREATHE (Bristol environmental atmospheric chemistry)
New computer models have been developed that incorporate these data in collaboration with the United Kingdom Meteorological Office.
A range of laboratory studies have provided considerable insight into the role played by aerosol in the urban environment and how these aerosol age and transform in the presence of pollutants. In particular, the role of soot has been investigated. Theoretical and laboratory studies have allowed us to understand the interaction between sunlight and key species in the atmosphere, showing that the atmospheres natural cleaning ability is more robust than first thought.
New instrumentation has been developed and deployed at the Mace Head Research Station (a NASA global air watch station) providing key insights into the oxidising capacity of the atmosphere and showing that methane, a key greenhouse gas, is increasing again, with implications for warming of the atmosphere.
