What is shallow fog and smog, which Delhi NCR is experiencing?

Delhi NCR is facing dense smog and shallow fog, as explained by IMD, reducing visibility and pushing the AQI over 400.

The low visibility caused by smog led to flight diversions at the airport, with zero-meter visibility recorded at 8:30 am.

Delhi’s air quality reached the 'Severe' category, while surrounding cities like Gurugram and Ghaziabad were 'Poor'. Faridabad's AQI was 'Moderate'.

Shallow fog occurs when visibility drops below 1,000 meters, usually in cold weather, due to condensation of water vapor near the ground.

?What is Shallow fog?

When shallow fog mixes with smoke and chemicals, it forms smog, which worsens air quality and visibility.

The smog not only reduces visibility but also worsens pollution, making the air hazardous to breathe.

What is smog?

Delhi has been in the 'Very Poor' air quality range for two weeks, worsening the smog situation.

The Graded Response Action Plan has been activated, focusing on measures like road cleaning and dust control to improve air quality.
