Delhi AQI Remains Above 300; Stronger Winds Likely To Improve Air Quality

Delhi’s air quality remained in the ‘very poor’ category on Wednesday morning, with the overall Air Quality Index (AQI) reaching 308 at 8:40 AM. However, stronger winds are expected to improve pollution levels over the next few days.

Of the 59 air quality monitoring stations that reported data, 29 recorded ‘very poor’ air quality, while the remaining stations fell in the ‘poor’ category. No monitoring station reported ‘severe’ air quality.

Chhawla recorded the highest AQI at 398, followed by Chandni Chowk at 383, ITO at 369, Pusa at 361 and NIH Narela at 356. Other areas reporting very poor air quality included Punjabi Bagh, Wazirpur, Badarpur, Burari and Jahangirpuri.

Meanwhile, locations such as Karala, Ghoga, Nangloi, Maidan Garhi and Narela recorded AQI levels in the poor category.

According to the Central Pollution Control Board (CPCB), an AQI between zero and 50 indicates good air quality, while 51-100 is satisfactory and 101-200 is moderate.

Readings between 201 and 300 fall under the poor category, 301-400 indicate very poor air quality, and 401-500 represent severe pollution.

The CPCB on Tuesday attributed differences between official and private AQI readings to variations in measurement and calculation methods, denying under-reporting.

The clarification followed concerns over missing data and the capping of readings at 500 during Diwali.
