Air Quality Forecasts for China

23.07.2008
With less than a month remaining before the Beijing Olympics, Chinese officials have introduced a series of measures to improve air quality for the Games. A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts.

Poor air quality could pose problems for the Olympic athletes and hinder the performance of those competing outdoors in endurance sports, such as cycling and marathons.

Since the main source of air pollution in the Beijing urban area is vehicle emissions, restrictions on car traffic began on 20 July in order to take 50 percent of Beijing’s 3,5 million vehicles off the road.

From then until 20 September, private vehicles will only be allowed to drive on alternating days and cars with high emissions will be banned.

On behalf of ESA, CERC (Cambridge Environmental Research Consultants) installed a High Resolution Air Quality Forecasting System at the Beijing Municipal Environmental Protection Bureau (EPB) that allows Chinese authorities to monitor the effect these cuts have on street level air quality.

"We are delighted to have installed the system in Beijing and believe the detailed air quality forecast it provides will prove a valuable tool in predicting and understanding Beijing’s Air quality," David Carruthers from CERC said.

"The system is highly flexible and can be adjusted rapidly, for example, to take account of the special emission reduction actions being implemented during July until after the Games."

Thanks to this new tool, operational street scale air quality forecasts for Beijing have been generated since 8 July – exactly one month before the Games’ opening ceremony.

Three-day forecasts are posted daily and are accessible on the Beijing Air Quality website www.beijingairquality.cn. The forecasts are high-resolution pollution contour maps that predict levels of nitrogen dioxide, ozone, particles and sulphur dioxide for each of Beijing’s eight districts. Users can choose to view maps of each pollutant separately or to view the total health index with all pollutants combined.

"The final forecasts utilise a combination of air quality measurements, surface data and modelling. Regional modelling using Chimere is provided by the Royal Netherlands Meteorological Institute (KNMI) and detailed local modelling is done by CERC’s model, ADMS-Urban," Carruthers explained.

Li Kunsheng, EPB Vice Director said he welcomed the installation of the new system and looked forward to it becoming an important tool for forecasting air quality in Beijing taking account of the effects of air pollution management measures including those being implemented for the Olympic Games.

The three-day advanced forecasts are made available as part of the Dragon-2 Programme, a joint undertaking between ESA and the Ministry of Science and Technology (MOST) of China designed to encourage increased exploitation of ESA and Chinese Earth Observation (EO) satellite data within China.

Satellite data from the SCIAMACHY and OMI instruments will be included into the regional model in the near future to improve further emission monitoring.

SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric Chartography) is one of 10 instruments aboard ESA's Envisat satellite.

OMI (Ozone Monitoring Instrument) was built by a team of European industry and scientists led by the Netherlands and supplied as an additional instrument to the NASA EOS-AURA mission.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

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....
