Answer:
The restrictions have sent financial markets into free fall. But they have also given residents in some of the world’s most polluted cities something they have not experienced in years: clean air.
Reuters visualisations, based on data from NASA’s Global Modeling and Data Assimilation team, show how concentrations of some pollutants fell drastically after the lockdowns started.
Satellite observations record information on aerosols in the atmosphere. NASA’s model is then able to provide estimates of the distribution of these pollutants close to the Earth’s surface.
