The National Centre for Atmospheric Science (NCAS) is a world leader in atmospheric science. We are one of the Natural Environment Research Council's (NERC) research centres, formed in 2002 to provide the UK with national capability in atmospheric science. We carry out research in air pollution, climate and high-impact weather, and long-term global changes in atmospheric composition and climate, and provide the UK community with state-of-the-art technologies for observing and modelling the atmosphere. These include a research aircraft, advanced ground-based observational facilities, computer modelling and support, and facilities for storing and analysing data. We play a significant and influential role in many international science programmes and provide the UK with advice, leadership and national capability in atmospheric science. We are organised around three science themes and five underpinning services and facilities, with over 200 members of staff embedded in 12 UK universities and research institutes including: University of York, University of Leeds, University of Manchester, University of Cambridge, University of Reading, Rutherford Appleton Laboratory, University of Birmingham, University of East Anglia, University of Oxford, University of Hertfordshire, University of Surrey and Cranfield University.
