Dr Steve Arnold


Steve's research focuses on the processing and transport of trace gases and aerosols in the atmosphere, and their interactions with the Earth's climate system, biopshere and society. This research is key to improving our ability to understand and predict changes in present-day and future climate, and risks to human health and ecosystems. I use numerical models in conjunction with observations from aircraft, satellites and surface sites to probe fundamental chemical and physical processes controlling these interactions.

Steve is also Director of the Centre of Excellence for Modelling the Atmosphere and Climate (CEMAC).

Steve first joined the school in 2000 as a PhD student in atmospheric chemistry, supervised by Martyn Chipperfield.
