Centre for Atmospheric Science


The Centre for Atmospheric Science

Welcome to the Centre of Atmospheric Science (CAS).

The CAS is a joint venture between multiple departments within the University of Cambridge. Initially established in 1993 between the Departments of Chemistry and Applied Mathematics and Theoretical Physics, with the Department of Geography joining shortly later.

The CAS was set up with the overarching aim of promoting environmental research and departmental work, whilst encouraging world-class funding opportunities so we could continue carrying out high-quality research.

With the University Departments of Chemistry, Geography and Physics consistently ranking within the top five worldwide, we have an exceptional record of discovery, innovation and excellence.

We have a number of active research groups working in the Centre from a range of different departments. We are one of the premier research groups in the UK for atmospheric research, and attract funding from a wide range of sources.

In the CAS, post-doctoral researchers and students from across the world carry out ground-breaking, innovative research. Here we provide an overview of the different research groups within each department. For more information about specific research groups, look in our research group webpage.


Department of Chemistry: Atmospheric Chemistry Research Group

The Atmospheric Chemistry Research Group (ACRG) has a very active research program into all aspects of atmospheric chemistry, such as modelling studies of stratospheric and tropospheric chemistry, using 1D, 2D and 3D models.

The group builds its own instruments for observations of chemical constituents in the atmosphere and is conducting research into the kinetics of reactions important for atmospheric chemistry.


Department of Chemistry: Climate Change Policy Group

The Climate Change Policy Group (CCPG) is undertaking several important research projects, collaborating with partners around the globe. For example, the group has active research into climate modelling scenarios and improving the performance of IAMs. Read more about the CCPG on their dedicated page.


Department of Applied Mathematics and Theoretical Physics

In the Department of Applied Mathematics and Theoretical Physics, scientists are engaged in studying fundamental dynamical processes. For example, mixing processes in atmosphere and the development of new gravity wave parametrizations for atmospheric models.


Department of Geography

In the Department of Geography, research is being carried out into small scale processes such as mixing within plumes and application to volcanic eruptions.
