NASA news: Pollution drastically drops as people stay home due to coronavirus lockdown


New York is now the epicentre of the disease with more infections than the countries of Spain, 157,000, and Italy, 143,000.

NASA said: “Over the past several weeks, NASA satellite measurements have revealed significant reductions in air pollution over the major metropolitan areas of the Northeast United States.

“Similar reductions have been observed in other regions of the world.

“These recent improvements in air quality have come at a high cost, as communities grapple with widespread lockdowns and shelter-in-place orders as a result of the spread of COVID-19.”

The US space agency said NO2 emissions can be used as an indicator of changes in human activity.
