Delhi kept gasping for breaths in 'very poor' air  for the 13th day in a row on Monday with heavy smog enveloping parts of the city.  The mainly smog condition with wind speed upto 04 -08 kmph from southeast/east direction prevailed over the region.  There will be no relief from the air pollution in the next six days. The Central Pollution Control Board (CPCB) data shows Delhi ranked sixth among the 262 cities on November 10. While Chandigarh had a higher AQI of 339, Bengaluru had the cleanest air among the metros, with an AQI reading of 72. However, this does not compare well with international cities. New York’s 49 AQI was better than 238 of the 262 cities for which data was available. London’s AQI reading of 76 was lower than that of 194 Indian cities, while Beijing’s reading of 161 was better than that of 78 cities.

The CPCB recorded an average Air Quality Index (AQI) of 334 .  In the morning, Bawana and Jahangirpuri reported ‘severe’ AQI levels of 401 and 412 respectively. The AQI level at Aurobindo Marg stood at 206, 358 at Alipur, 385 at Anand Vihar, 356 at Burari Crossing, 367 at Dwarka-Sector 8, 338 at IGI Airport-T3, 307 at Lodhi Road, 382 at Mundka, 357 at Najafgarh, and 371 at RK Puram. Additionally, the Central Pollution Control Board (CPCB) recorded AQI levels of 315 near Jawaharlal Nehru Stadium and 378 at Akshardham, both categorized as ‘very poor.’

The transport sector is the most significant contributor at 12.122 percent, as per the Decision Support System data by the Indian Institute of Tropical Meteorology (IITM). While the residential sector contribution is 3. 143 percent, industries contributed 2.778 percent, construction 1. 652 percent, energy sector 1. 399 percent, waste burning 1.138 percent, and road dust 0.895 percent.

According to the Air Quality Early Warning System for Delhi, Mist/Shallow fog reported at Safdarjung airport. Safdarjung airport recorded lowest visibility 700m at 0700 hours IST which improved thereafter becoming 0800m at 0830 hours IST. Palam airport recorded lowest visibility at 1000m at 0730 hours IST. In many parts of the city, buildings, monuments, offices, flyovers, roads, and bridges were hardly visible as they were covered by a thick layer of smog.  Predicted maximum mixing depth is traced to be 1800 m on November 11. It is likely to be 2750 m on  November 12.
