Air pollution in northern India is at its lowest in 20 years, according to a study published by the US space agency National Aeronautics and Space Administration (NASA).
Experts revealed that the aerosol levels reduced significantly post the countrywide lockdown, implemented to contain the spread of coronavirus.
On the other hand, the case is different in southern India. Satellite data show aerosol levels have not yet decreased to the same extent. They, in fact, seem to be slighter higher than in the last four years.
The reasons could be recent weather patterns, agricultural fires, among other factors.
With transport, construction and majority of activities suspended, the clean air and blue skies come as one of the few positive side effects of the lockdown.
