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: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
