Dramatic fall in China pollution levels ‘partly related’ to coronavirus

(The Guardian, 3 Mar 2020) Nasa satellite images show decline as industrial activity slows in effort to limit coronavirus

Nasa satellite images show a dramatic decline in pollution levels over China, which the US space agency believes is “partly related” to an economic slowdown due to the coronavirus.

Nasa scientists said the reduction in nitrogen dioxide levels, the noxious gas emitted from motor vehicles, power plants and industrial facilities, was first evident near Wuhan city, the source of the outbreak, but then spread across the country.

Images from Nasa and the European Space Agency (ESA) pollution monitoring satellites were used to compare the first two months of 2019 with the same period this year.

The maps show NO2 – nitrogen dioxide – values across China from 1-20 January, before the quarantine, and 10-25 February, during the quarantine. The decline comes as China’s manufacturers stop work in an effort to contain coronavirus.
