Asian polluted gas spreads throughout the world

According to a study by the US National Center for Atmospheric Research (NCAR), polluted air from developing economies in Asia soars up the stratosphere during the rainy season and spreads around the world.

AFP news agency said that according to NCAR's research, very strong air flow related to the Asian rainy season is the way for polluted gases such as carbon black, SO ₂ , NO . to reach the stratosphere - floor The atmosphere is located about 32-40 km from the ground.

'Monsoon is one of the most powerful atmospheric circulation systems on the planet, and it forms right on the heavily polluted area,' AFP quoted NCAR scientist William Randel, co-author of the study.

AFP said that based on data collected from satellites, NCAR scientists found that once they reached the stratosphere, polluted gas would spread throughout the Earth within a few years.

Researchers fear the impact of polluted gas from Asia on the stratosphere may skyrocket in the coming decades due to the strong growth of regional economies such as China or India.

NCAR's study is published in Science June 26. The US National Science Foundation, the US Aerospace Agency (NASA), and the Canadian Aerospace Agency also support this research.
