Space Weather and Atmosphere team

Our ambition

Large explosions on the Sun known as coronal mass ejections can spew out billions of tons of charged particles and magnetic field into space. When these disturbances reach the Earth they can trigger geomagnetic storms and increase particle radiation levels, causing disruption to power grids, satellites, aviation, and a host of other dependent businesses.   These effects are known as Space Weather. Solar variations are also linked to changes in the atmosphere and surface temperature in the Polar Regions but how this occurs and how it affects weather and climate are open questions.

The goal of the Space Weather and Atmosphere team is to understand how solar variations affect the Earth’s space radiation environment, upper atmosphere and climate in the Polar Regions.

Our research provides the information needed by the Space Industry, UK Insurance and Government to mitigate the effects of severe Space Weather, and to assess the solar contribution to climate change in the Polar Regions.

Team priorities

Science

  • Space radiation environment. To measure, simulate and predict changes in space radiation environment as they affect satellites, and to develop realistic scenarios of severe space weather events. These results are being used to assess which satellite orbits are most at risk and to develop better mitigation guidelines. They are also being used to provide real-time situation awareness for satellite operators.
  • Atmospheric heating. To measure the heating and upward expansion of the polar atmosphere due to electrical currents set up during geomagnetic storms. This process, known as Joule heating, is the largest uncertainty in orbit prediction for satellites and space debris. The results will help provide better collision avoidance measures between satellites and space debris in low Earth orbit.
  • Climate impacts on satellites orbits. To model and measure changes in the upper atmosphere related to increased levels of CO2 and to the impact the long term impact this has on the satellite and space debris environment. These results will inform best practice for satellite operators for long-term planning.
  • Space-atmosphere coupling. To measure changes in atmospheric chemistry caused by particle precipitation and assess how they can affect the heating and cooling of the upper atmosphere. These results are being used in models to determine how they couple through the atmosphere to affect surface temperature and to determine their effect on polar climate.
  • Solar effects on climate. To measure changes in the geoelectric field and understand how it can affect the atmosphere. Changes in the geoelectric field between the ground and the ionosphere have been linked to changes in atmospheric temperature, from the surface upwards.

Technology, innovation and training

  • Using High Frequency over-the-horizon radars to understand coupling between the Sun, solar wind and the upper atmosphere, and the transport of charged particles in the radiation belts
  • Using Medium Frequency radars to measure high altitude winds and atmospheric circulation in the polar vortex
  • Developing state-of-the-art sub-millimetre radiometer technology to measure upper atmosphere winds and chemistry with Cambridge University
  • Using an array of remote, low power magnetometers to measure changes in the geomagnetic field and electrical currents generated by Space Weather
  • Using the BAS radiation belt model to simulate and predict the Earth’s radiation environment for satellites (a model equivalent to a general circulation model in atmospheric science), built upon important models of particle and wave process.
  • Exploiting data collected by constellations of satellites on charged particles, electromagnetic fields and atmospheric composition
  • Training young scientists via PhD studentships via NERC Doctoral Training Partnerships (DTP) such as the Cambridge Earth System Science and Southampton INSPIRE and via short term student vacation projects

Influencing and leading international programmes

  • Continue setting scientific priorities as one of the PI Groups in the international SuperDARN radar network, and the AARDDVARK radio receiver consortium
  • Continue leading the European Union SPACESTORM project
  • Continue to play a leading role in the International Association of Geophysics and Aeronomy (IAGA), and the VLF/ELF Remote Sensing of the Ionosphere and Magnetosphere (VERSIM) scientific planning

Stakeholder engagement

  • Continue providing expert advice to the Cabinet Office and UK Government departments through our membership of the Space Environment Impacts Expert Group (SEIEG) , meeting with the Government Office of Science and officials from Departments such as Business and Trade, Science, Innovation & Technology, and Transport.
  • Continue our collaborations with the space industry including UK insurance, European satellite operators and satellite designers, through our leadership of the European SPACESTORM project
  • Organising an annual end-user lunch at the European Space Weather Week jointly with the European Space Agency
  • Continue representing the UK on the Council of the European Incoherent Scatter (EISCAT) radar and supporting UK users of the facility

Public engagement

  • Disseminating information by publishing our results in high-impact peer reviewed Journals, giving presentations at international conferences and issuing press releases when appropriate
  • Organising and running scientific sessions at International conferences
