NASA’s Aura and ESA’s Sentinel-5 captured the improved status of air pollution in the north-eastern China. The satellites have detected significant decreases in nitrogen dioxide (NO2) over China. There is evidence that the change is at least partly related to the economic slowdown following the outbreak of coronavirus. According to NASA scientists, the reduction in NO2 pollution was first apparent near Wuhan, but eventually spread across the country.
The local scenery on the ground of Wuhan is as follows.
