In the Centre for Space, Atmospheric & Oceanic Science (CSAOS) we research the effects of the natural environment on the propagation of the radio and acoustic waves used in communication, navigation and remote-sensing systems. We use these remote-sensing systems for scientific studies of the geophysical environment.

Our research is driven by the need to understand the response of the natural environment to climate variability and space weather. We also research the effects these phenomena have on critical modern technological systems, such as satellite navigation and timing systems (including GPS).

Currently, our research includes the following areas:

  • space-weather impacts on Global Navigation Satellite Systems
  • satellite and radar studies of the stratosphere and mesosphere
  • imaging and image processing for geophysical and other applications
  • radio emissions from lightning and sprites
  • marine acoustics and sonar
  • radio systems for security applications.

Our research delivers impact in wide-ranging areas, including contributing to changes in government policy, such as the addition of space weather to the National Risk Register, driving international UK/US initiatives in space-weather research, providing the Met Office with powerful new scientific tools to improve forecasting and helping protect the UK from the accidental or deliberate jamming of GPS-reliant infrastructure.

We have a lively research community of academics, researchers and postgraduates, including senior staff on secondment from the Met Office and Honary Professors from leading UK industry. We engage in strongly interdisciplinary research, receive significant external research funding and collaborate with leading national and international research groups.

We welcome graduate students to join us to study for PhDs and have an excellent track record in providing our PhD graduates with the experience and skills needed to begin successful careers in research and industry.
