CPCB Data Shows ‘Severe’ AQI at Multiple Stations
The Central Pollution Control Board (CPCB) reported that by noon, 18 out of 40 AQI stations across Delhi had recorded a ‘severe’ AQI. This was a worsening trend from Thursday afternoon, when only 12 stations had reached severe levels. The worst-affected areas included Wazirpur (431 AQI), Rohini and Jahangirpuri (434 AQI), and Bawana (430 AQI).
Stubble Burning Contributes Less to Pollution
Data from the Centre’s Decision Support System (DSS) showed a reduction in the contribution of stubble burning to Delhi’s pollution on Thursday. While it had contributed over 20% to the pollution from Monday to Wednesday, it decreased to 17.8% on Thursday.
Outlook for the Coming Days
The Air Quality Early Warning System (AQEWS) for Delhi has forecasted that the city’s AQI will remain in the ‘very poor’ category through the weekend, with the same air quality expected from Saturday to Monday. The six-day outlook suggests that the air quality will likely remain in the ‘very poor’ range throughout the period.
Wind Patterns and Air Quality
According to AQEWS data, the prevailing surface winds in Delhi are expected to continue coming from variable directions, including north-westerly, easterly, and south-easterly winds, with speeds of 4-8 km/h. These winds are not expected to bring significant relief in improving the city’s air quality.
As Delhi continues to grapple with hazardous pollution levels, health experts have advised residents to limit outdoor activities, particularly for children, the elderly, and those with respiratory issues.
