According to Fei Liu, an air quality researcher, this is the first time she has seen such a stark change because of one particular event (COVID-19 outbreak)

COVID-19 impact on China is so stark that we can see it from space, according to data from European and U.S satellites.

Our instruments in space to monitor air pollution has noticed a dramatic drop in the level of NO2 since the outbreak first started in January.

Nitrogen dioxide is a harmful substance emitted by power plants and vehicles that run on fossil fuel. This drop in the concentration of NO2 likely results from the travel restriction and economic slowdown that China suffers due to the COVID-19 outbreak.

According to Fei Liu, an air quality researchers, this is the first time ever she has seen such a quick drop of air pollution as a result of one particular event. The image on the left shows the level of NO2 in January and the one on the right is in February.

Liu said that in 2008 when the big economic recession happens, the same phenomenon also occurred, but it could not rival the speed nor the volume of decreasing in the level of nitrogen dioxide in the air.

Liu shared that this year has seen the most significant drop but the reason here is clear. The Chinese government has been applying measures to stop COVID-19 from spreading further in China and it has affected the region's economy.

In China, businesses have been closed and inter-city travel has been restricted. The government is especially strict with preventative measures in Wuhan, the epicenter of the outbreak. And the impact of these measures can be seen in the diagram showing air pollution between January 1 and February 25.

As COVID-19 spreads to other countries, similar impact is expected to show up worldwide.
