Gone With the Wind? Over A Hundred Scientists Take To The Skies To Track Global Air Pollution

12.07.2004


This morning a team of forty scientists from seven UK universities will travel to the Azores to join hundreds more in the largest international atmospheric field campaign of its type ever attempted.

The exciting mission will track and investigate a mass of polluted air as it leaves the United States and travels across the Atlantic to the UK and mainland Europe. Scientists will measure chemical reactions within the air-mass as it travels, quantifying the resulting pollutants delivered to Europe.

This ambitious project involves scientists from six countries co-ordinating five research aircraft (including the UK BAE-146 aircraft), a research ship as well as numerous ground stations and satellites.



With the help of sophisticated UK tracking models, US scientists will start the campaign by making measurements in a polluted air-mass off the east coast of the States. UK scientists will then fly out from the Azores to intercept the same air mass and make similar measurements from their own flying laboratory - the UK BAE 146. To complete the picture, the German scientists will intercept it in their Falcon aircraft, as it lands over Europe. Excitingly, mid-air wing-tip to wing-tip calibrations between the three aircraft will also be carried out during the mission.

UK organiser, Dr Alastair Lewis from the Intercontinental Transport of Ozone and Precursors programme (ITOP), said:

“It’s highly likely that air leaving the States contains a cocktail of nitrogen oxides and hydrocarbons, which are emitted from vehicle exhausts and power stations. We want to know how these will react together on the way to Europe and notably whether they form ozone and particles, both of which can be harmful to humans.”

Dr Lewis continued:

“It’s almost a year now since the 2003 summer heatwave when we measured elevated levels of ozone and particles above London. It was estimated then that up to 800 deaths were brought forward by this air pollution incident and although we know that some of this pollution was produced locally in the UK, we still don’t know what the contribution was from other countries.

“For the first time, this mission will allow us to work with our international colleagues to understand and quantify the effects of trans-continental transport of chemicals, both on regional and global air pollution.”

The British, American, Canadian, German, French and Portuguese scientists are all part of the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT), led by NASA and the National Oceanic and Atmospheric Administration (NOAA).

The Natural Environment Research Council Centres for Atmospheric Science (NCAS) and the NERC directed programme, the “Upper Troposphere Lower Stratosphere Ozone Programme”, has provided instrumentation and £1.2M of funding for the project.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
