Researchers have shown a map of the Earth pollution

Descartes Labs researchers have published to date map of air pollution around the world where the bright spots and strings displayed unfavorable to human zone. In these places recorded the scale emissions of nitrogen dioxide generated in the combustion process.

The sources of this gas are vehicles, power plants, forest fires, construction equipment and even lawn mowers. It expected that the greatest concentration of gas occurs in large cities and industrial centers. However, to meet the bright filaments can be in the ocean - usually ships routes.

Making such a map could use the Sentinel 5P space satellite, launched in October 2017. Researchers collected huge set of images obtained from him and formed one single image that covers the entire Earth.

Sentinel 5P - just one of a family of satellites launched by the European Space Agency and designed to monitor our planet. His "brothers", for example, to track changes of vegetation levels, temperature fluctuations and even a crack in the Antarctic ice.
