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.
- 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.
