Record air pollution above the Arctic

Last week Scientists of the Alfred Wegener Institute for Polar and Marine Research observed the highest air pollution on record since measurements began in Ny-Ålesund on Svalbard. Monitoring instruments displayed significantly increased aerosol concentrations compared to those generally found. Aerosols from eastern Europe have been transported into the Arctic atmosphere due to a particular large-scale weather situation.

Usually the air is pure and clear above the French-German AWIPEV-Research base in Ny-Ålesund at the western coast of Svalbard. However, at the beginning of May it turned to a deep orange-brown. Confirming the observations of the German team, Swedish scientists of the Department of Applied Environmental Science at Stockholm University (ITM) measured up to fifty micrograms aerosol per cubic metre air in Ny-Ålesund. Such values are usually measured during rush hour in cities. In addition, the Norwegian Institute for Air Research (NILU) found extremely high concentrations of ozone above ground. With more than 160 micrograms ozone per cubic metre, these values are the highest measured since the foundation of the research base in 1989.

A specific weather condition has caused the record high air pollution. Large amounts of aerosols from eastern Europe were driven into the arctic atmosphere. Increased aerosol concentrations had already been measured at springtime of recent years. However, this „Arctic Haze" has never been as pronounced before.

Aerosols constitute small particles in the atmosphere. They can be liquid or solid and serve as condensation nuclei during cloud formation. It is these properties that lead to aerosols influencing the climate system. „The present air pollution is more than 2.5 fold higher than values measured in spring 2000. As a consequence, we expect significantly increase warming ", explains Dr. Andreas Herber of the Alfred Wegener Institute in Bremerhaven.
