Satellit spürt den Schadstoff-Ausstoß von Megacities auf

Aus Satellitenmessungen der aktuellen Stickoxid-Belastung lassen sich mit einem mathematischen Kniff die ursprünglichen Emissionen ermitteln

(PresseBox) (München, )
Die Stickoxidmengen, die in Ballungszentren in die Luft gelangen, lassen sich künftig unabhängig von Hochrechnungen und Modellsimulationen bestimmen. Forscher des Max-Planck-Instituts für Chemie bestimmen aus Satellitendaten zur aktuellen Schadstoffbelastung und Wetterdaten, wie lange die Stickoxide in der Atmosphäre bleiben. Aus der Verweildauer und der aktuellen Belastung errechnen sie dann den ursprünglichen Ausstoß. Die Erfassung der Emissionen ermöglicht gezielte Maßnahmen zur Luftreinhaltung. Bislang werden die Emissionen anhand von Hochrechnungen abgeschätzt, was oft zu ungenauen Ergebnissen führt.

In Großstädten entweichen Unmengen an Schadstoffen in die Atmosphäre. So entstehen besonders im Verkehr täglich tausende Tonnen an gesundheitsschädlichen Stickoxiden, die in vielen Ländern omwu yuvtgdmczxm uj qzp Kpvz ggiccco.
