Stratospheric data supplied by Envisat are the basis for a near-real time global ozone forecasting service now available online.
Up in the stratosphere about 25 km above our heads is the ozone layer. Stratospheric ozone absorbs up to 98% of the Sun’s harmful ultraviolet light – making the difference between a suntan and sunburn, and safeguarding all life on Earth. But chemical activity in the stratosphere ultimately due to the presence of manmade gases such as chlorofluorocarbons (CFCs) can thin the ozone layer.
The Brussels-based Belgian Institute for Space Aeronomy (BIRA-IASB from its initials in Flemish and French) has developed a service called the Belgian Assimilation System of Chemical Observations from Envisat (BASCOE) that maps and forecasts not only the concentration of ozone in the stratosphere but also 56 other chemical species, including those responsible for ozone depletion.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
