Satellite data to deliver ‘state-of-the-art’ air quality information

06.02.2008
The European Environment Agency has finalised an agreement with an ESA-led consortium to provide unparalleled information on air pollution, which contributes to the premature deaths of hundreds of thousands of Europeans annually.

Under the agreement, the European Environment Agency (EEA) will use a service, which combines and processes satellite data with surface measurements from 29 European countries to deliver accurate information on air quality daily, to support the implementation of European air-quality policies.

"Sophisticated processing and satellite data from ESA will combine to deliver state-of-the-art information on air quality. This will allow EEA to get the most from ground-based measurements collected through its networks," EEA Project Manager Tim Haigh said.

"I am excited about the opportunity that this service creates to help us provide timely information on Europe's environment at an unprecedented level."

The 'Integrated Air Quality Platform for Europe’ service, part of the ESA GMES (Global Monitoring for the Environment and Security) PROMOTE (PROtocol MOniToring for the GMES Service Element) project, was developed to provide end-users information about air quality and is currently providing forecasts for up to 72 hours at a resolution of 50 km.

The service includes data on ozone, nitrogen dioxide and particulate matter (the sum of all particles suspended in air, including dust, smoke, pollen, etc.). Exposure to these pollutants can cause adverse health effects such as decreased lung function, increased respiratory symptoms and allergic responses, according to the World Health Organisation.

The service applies an ensemble approach by combining three different and thoroughly validated air-quality models: MOCAGE (Meteo-France), EURAD (RIU), and CHIMERE (INERIS). These models combine in-situ and satellite data using different data assimilation techniques in order to generate consistent information about air quality.

The Service Level Agreement (SLA) was signed between EEA and the French National Institute for Industrial Environment and Risks (INERIS) and the German Space Agency (DLR).

"A median model ensemble provides air quality forecasts and analyses that are superior to any single model simulation, combining the strengths of different models, and allows [for the] representation of the range of variability of the model responses that is a part of their inherent uncertainty," Laurence Rouil from INERIS said. "Therefore, decision makers and regulatory-purpose applications will benefit from this PROMOTE service."

In addition to supporting air quality policies, the service offers the wider public the ability to protect better their health by avoiding exposure and taking measures to reduce air pollution.

PROMOTE and GMES

PROMOTE is an ESA project that seeks to develop beneficial operational services for organisations and citizens that will use atmospheric data to address the concerns of both policymakers and individuals. The PROMOTE consortium is made up of more than 30 partners from 11 countries.

GMES – a joint initiative of the European Commission and ESA – responds to Europe’s needs for geo-spatial information services by bringing together the capacity of Europe to collect and manage data and information on the environment and civil security, for the benefit of European citizens.

The GMES Service Element (GSE) prepares user organisations in Europe and worldwide for GMES by enabling them to receive and evaluate information services derived from existing Earth Observation satellites since 2002.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
