Carbon monoxide from fires in Australia

Ferocious bushfires have been sweeping across Australia since September, fuelled by record-breaking temperatures, drought and wind. The country has always experienced fires, but this season has been horrific. A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half a billion animals have perished. The fires have not only decimated the land, but they have also had a serious effect on air quality.

The animation uses information from the Copernicus Sentinel-5 Precursor mission and shows increasing concentrations of carbon monoxide between September and December 2019 along Australia’s southeast coast. Carbon monoxide is commonly associated with traffic, but here we see the increase in atmospheric concentrations owing to the fires. Naturally, once in the air, it can cause problems for humans by reducing the amount of oxygen that can be transported in the bloodstream.
