New research contributes to defense of Earth's technologies

05.06.2009
Leicester scientists implement a new radar mode to create clearer picture of space weather

University of Leicester researchers have taken a step forward in helping to create a defence for earth's technologies –from the constant threat of space weather.

They have implemented a "double pulse" radar-operating mode on two radars, which form part of a global network of ground based coherent scatter radars called SuperDARN (Super Dual Auroral Radar Network).

These radars allow observations of space weather, which can have devastating impacts for technologies on earth.

James Borderick, of the Radio and Space Plasma Physics group, within the Department of Physics and Astronomy, said: "Intense space weather events are triggered by the explosive release of energy stored in the Sun's magnetic fields.

"A strong burst of electromagnetic energy reaches the Earth with the potential to disrupt many of our fundamental services, such as satellite and aviation operations, navigation, and electricity power grids. Telecommunications and information technology are likewise vulnerable to space weather.

"All modern societies rely heavily on space systems, for communications and resource information (meteorological, navigation and remote sensing). There are high cost and high risks associated with the consequences of space weather events, as insurance companies recognise.

"We have implemented a new "double pulse" radar-operating mode on the Radio Space Plasma Physics Group's Co-operative UK Twin Located Auroral Sounding System (CUTLASS) radars.

"The new sounding mode enhances our temporal resolution of plasma irregularities within the ionosphere. The resolution increase may help our understanding of coupling processes between the solar wind and the Earth's magnetosphere by allowing the observation of smaller scale phenomena with an unprecedented resolution.

"Utilising our new radar mode and the vastness of ground based and space based instruments at our disposal, we are ever increasing our understanding of the countless phenomena associated with the Solar-Terrestrial interaction, and one day, may lead us to the accurate predictions of intense weather events- and an active defence."

The research introduces the importance of utilising ground-based measurements of the near space environment in conjunction with spacecraft observations and then proceeds to explain the direct influences of space weather on our own technological systems.

Mr Borderick will be presenting his doctoral research at the Festival of Postgraduate Research, which is taking place on Thursday 25th June in the Belvoir Suite, Charles Wilson Building between 11.30am and 1pm.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
