"This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event," said Fei Liu, an air quality researcher at NASA's Goddard Space Flight Center, said in a statement.

"This year, the reduction rate is more significant than in past years and it has lasted longer," Liu said.
