NASA's aerial images show decline in China's pollution levels amid coronavirus outbreak

In an unprecedented development, coronavirus has reportedly infected more than 85,000 and killed nearly 29,000 people globally except Antarctica. However, dely virus has cleared air in China. NASA recently released aerial ims of Earth which showed a drastic decline in pollution levels over rrn China in past month. 

Drastic difference

aerial ims which were released by NASA along with European ncy (ESA) on former’s website compare concentration of nitrogen dioxide across China between January 1-20 i.e. period before quarantine and February 10-25  i.e during quarantine with results showing drastic difference.

According to media reports, Nitrogen Dioxide levels typically surge in February as factories reopen and more vehicle take over ros after Chinese Lunar year. Fei Liu, an air quality researcher at NASA’s Goddard Flight Center, in public statement, said that it was first time that she h seen such a “dramatic drop-off” in 2. According to NASA, a similar case was observed during 2008 recession but decline was grual. Ar case was observed around Beijing during 2008 Olympics but effects were localised around Chinese capital.

Meanwhile, NASA released ar set of ims showing what heatwave means to local ice cap and glaciers in Antarctica. It aims to detail dramatic changes in ice and sw along rrn tip of Antarctic peninsula.  picture takes a look at Eagle Island on February 4 (left) which shows an abundance of ice cover, whereas picture on right gives a view from February 13 which shows melted ponds and exposed ground.
