India's air pollution reached 20 years ago due to the lockdown


BanglaHunt Desk: NASA satellite imagery says air pollution in India has decreased after 20 years. The main reason for this is of course the lockdown, as well as the aerosols floating in the Indian air due to the rains have decreased so much that the Indian sky is as clear as 20 years ago. The tiniest particles of air pollution that are trapped in our atmosphere. These particles can be made of solid material or liquid gaseous material. Clouds and fog are also a kind of aerosol.

Weather maps produced by the National Aeronautics and Space Administration's (NASA) supercomputers show that pollution in India was significantly lower this year than in the same period last year.

When particulate matter (PM) is low, blue is the bottom edge of the scale, and the higher it is – the redder it is. Last year, compared to the reddish color on March 30, 2019 in India, this year the sky looks mostly blue. Even from the ground the sky looks blue enough.

A few days ago, a picture of the clear blue sky of Mumbai went viral on social media. Which clearly proves that the commercial city is getting rid of the pollution. In addition, the level of a.q.i in the capital city of Delhi has dropped significantly.

The city of Delhi is at the forefront of air pollution in the world. There the amount of a.q.i has dropped below 38 which is very comforting. As a result of the lockdown, the amount of nitrogen oxides in the air of Delhi has come down at a record rate. According to Safar, on March 25, Delhi's overall AQI score was 7.
