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: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...

Im Focus: Tube anemone has the largest animal mitochondrial genome ever sequenced

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.

The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....

Im Focus: Tiny light box opens new doors into the nanoworld

Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.

Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...

Im Focus: Cost-effective and individualized advanced electronic packaging in small batches now available

Fraunhofer IZM is joining the EUROPRACTICE IC Service platform. Together, the partners are making fan-out wafer level packaging (FOWLP) for electronic devices available and affordable even in small batches – and thus of interest to research institutes, universities, and SMEs. Costs can be significantly reduced by up to ten customers implementing individual fan-out wafer level packaging for their ICs or other components on a multi-project wafer. The target group includes any organization that does not produce in large quantities, but requires prototypes.

Research always means trying things out and daring to do new things. Research institutes, universities, and SMEs do not produce in large batches, but rather...
