Worldwide Pollution Levels Seen From Space

[Fraser]

SUMMARY: After 18 months of observations by the Envisat Earth monitoring satellite, the European Space Agency has produced a detailed image of the entire Earth that shows nitrogen dioxide pollution. Nitrogen dioxide is generally a man-made gas - produced in power plants, heavy industry, and burning - which can cause lung disease and respiratory problems. Previous maps like this have been made, but this image is at a resolution of 60 x 30 km (37 x 19 miles), so scientist can pick out individual cities which are a source of pollution.
