Worldwide atmospheric measurements to determine the role of atmospheric fine particles in climate change

16.11.2007
Finnish-led international aerosol project starts extensive worldwide atmospheric measurements: will determine the role of atmospheric fine particles in climate change

The Finnish Meteorological Institute in Helsinki, Finland, will host the first annual meeting of the European Integrated Project on Aerosol Cloud Climate and Air Quality Interactions, EUCAARI, headed by Academy Professor Markku Kulmala, on 19–22 November 2007. The purpose of EUCAARI is to significantly improve current knowledge of the impact of fine particles in the atmosphere on climate and air quality.

The first year of the project was dedicated to developing state-of-the-art aerosol measuring equipment, establishing a global network of measuring stations, and planning. The measuring period, beginning next spring, will collect data on European air through both ground-based and airborne measurements simultaneously.

During the past year, this EU-wide research project has developed an extremely sensitive measuring device for aerosols, allowing for reliable measurements of particles less than 3 nanometres across. Such a development in measuring technology will play a key role when solving the physical and chemical questions of aerosol generation and formation, and has already enabled significant, recently-published new observations on the quantity of particles less than 3 nm in size.

The past few months have also seen the establishment of a global measuring station network for EUCAARI. Stations have been established in Brazil, South Africa, China, and India. They cover measurement areas that are geographically important for the monitoring of air pollution. For example, the Brazilian station is located in the rainforest region, and the South African station in the savannah area. The stations will start operating from the beginning of 2008. In addition to the University of Helsinki, the Finnish Meteorological Institute plays a key role in running the observation stations and planning the infrastructure.

Next May, a new, month-long measuring period will begin. During that time, the atmosphere above Europe will be observed simultaneously from both ground-based and aircraft-borne equipment. The data-gathering flights will move across Europe in various directions. This will provide measuring data on, for example, the development of aerosol quantities at various altitudes in the atmosphere, and trace the long-range migration of air masses and various kinds of pollution. The month-long measurement period is part of a wider 15-month (1 March 2008–31 May 2009) intensive EUCAARI ground-based measurement campaign involving measuring stations in and outside Europe. The University of Helsinki’s Hyytiälä Forestry Field Station will contribute to this intensive period by providing ground-based measurements.

The four-year long EUCAARI was launched in January 2007, and will end in December 2010. The total budget of EUCAARI, currently the largest aerosol project in Europe, is €15 million, 10 million of which is covered by the European Union. The project employs researchers from 25 different countries.

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...
