After a temporary respite due to strong winds over the weekend, the AQI in Delhi NCR has started to return to the former state of being in the ‘very poor’ and ‘severe’ categories.

The air quality in the national capital and its adjoining regions is likely to worsen even further in the next two days, according to Skymet Weather.

According to weather experts from Skymet, the reason behind this is a western disturbance on the western side of Himalayas which is going to impact the flow of air in Delhi-NCR regions.

The reduced flow of air is likely to lead to an increase in the accumulation of pollutants in the region and on November 21 and 22 when the situation could worsen even further.

Pollution Watch brings you the measure of Air Quality Index (AQI) in major cities across the country.

The AQI is measured by taking into account the PM (particulate matter). The pollution of a place is measured either in PM10 or PM2.5, depending on which particle is more dominant in the air in that place.

PM10 is the particle which is 10 micrometers or less in diameter and PM2.5 is the finer particle with a diameter measuring 2.5 micrometers or less.

PM2.5 is considered more harmful since it is finer and can travel more deeply into the lungs and cause very harmful effects. These tiny particles in the air reduce visibility and cause the air to appear hazy when their levels are high.

0-30 Good
31- 60 Satisfactory
61- 90 Moderate
91- 120 Poor
121- 250 Very Poor
Beyond 250 Severe

*All levels are measured in PM2.5
