The Creative Technology Group has a research theme focused on numerical algorithms for automated data correction in large-scale datasets and data streams; and another that specializes in different forms of data visualization so that non-specialists and those with particular needs can benefit from complex data.

ESA Cluster-II  Mission

[Beloff, 2000-2016]

Researchers using the four spacecraft of ESA's Cluster mission have uncovered the long journey that energetic ions undergo during geomagnetic storms and how they ultimately precipitate into the Earth's atmosphere. Such precipitation affects the composition of the ionosphere, preventing GPS and communications satellites from operating correctly. The Earth's magnetic field acts a buffer zone, shielding the Earth from the permanent flow of ionised matter coming from the Sun. As a result of the interaction of the solar wind with the Earth's field, a protective bubble known as the magnetosphere is formed. This comprises a complex mixture of electric and magnetic fields, charged particles and resultant current systems. One such system, the so-called Ring current, forms in a doughnut shape around the Earth, and is caused by trapped particles, from either the solar wind or from the Earth's ionosphere, gyrating around the magnetic field lines of the Earth. Changes in the ring current are responsible for global decreases in the Earth's surface magnetic field. For more details see the Cluster web site.

NASA THEMIS mission 

[Beloff, 2007 – 2017]

The Time History of Events and Macro-scale Interactions during Substorms, or THEMIS, is a mission to investigate what causes auroras in the Earth's atmosphere to dramatically change from slowly shimmering waves of light to wildly shifting streaks of color. Discovering what causes auroras to change will provide scientists with important details on how the planet's magnetosphere works and the important Sun-Earth connection. The THEMIS mission is designed to impartially distinguish between two disparate phenomenological and plasma-physical models of substorm onset in order to solve a tantalizing mystery: Where and when do substorms start in the Earth's magnetosphere? This question has been the subject of scientific contention for over thirty years. For more details, see the THEMIS web site.
