Delhi pollution: AQI ‘severe’ in some areas, overall air quality at 396 | Top updates

The AQI in Delhi dropped to ‘very poor’ category by Monday evening due to low winds and continued to be at the same level on Tuesday morning.

After marginal improvement on Monday morning, the Air Quality Index (AQI) in Delhi dropped to ‘very poor’ category by the evening due to slow winds and continued to be at the same level on Tuesday morning, with most monitoring stations recording AQI between 300 and 440.

According to the SAMEER app, which offers hourly updates on the National Air Quality Index, the overall AQI at around 6:30 am on Tuesday, November 26, stood at 396. However, several monitoring stations reported an AQI of over 400 – the ‘severe’ category.

The Central Pollution Control Board (CPCB) categorises AQI as follows — 0-50 (good), 51-100 (satisfactory), 101-200 (moderate), 201-300 (poor), 301-400 (very poor), 401-450 (severe) and above 450 (severe plus).

Delhi air pollution | Key points

  • AQI in Delhi today: Of the 38 air quality-monitoring stations in Delhi, 18 reported AQI of over 400 or the ‘severe’ category at 6:30 am on Tuesday. These stations included: Anand Vihar (432), Ashok Vihar (420), Mundka (443), Rohini (432), and Vivek Vihar (432) among others.
  • Short-lived relief: On Monday, the AQI in Delhi improved marginally, with the pollution level going below the 300-mark on Monday morning. Moreover, there was finally some green in Delhi, with the Lodhi Road (IITM) monitoring station logging an AQI of 95, what the CPCB categorises as the ‘satisfactory’ level.
  • AQI levels plummet due to low winds: Thanks to low winds, the AQI that improved to 218 by 9 am on Monday rose to 377 at 7 pm. Seven of the 38 air quality-monitoring stations in Delhi reported AQI levels in the “severe” category at 5:30 pm, with the number rising to 14 at 7 pm.
  • What’s causing the pollution in Delhi: The Centre’s Decision Support System (DSS) for Air Quality Management estimated that vehicular emissions contributed 16.4 per cent to Delhi’s pollution on Monday. Stubble burning, another major factor, accounted for 11 per cent of the capital’s pollution on Sunday. Bhavreen Kandhari, an environmentalist, told news agency PTI that the AQI rose due to a combination of stagnant winds that have a speed of less than 10 kilometres per hour and dropping temperatures that trap pollutants close to the ground.
  • Consider Physical classes in schools, says SC: Despite Delhi’s air quality not making significant consistent improvement, the Supreme Court on Monday asked the Commission for Air Quality Management (CAQM) to consider restarting physical classes in schools and colleges in the National Capital Region (NCR) and adjoining areas, noting that students are being deprived of mid-day meals and lack the means to attend virtual classes.

  • Schools allowed hybrid classes: Following the Supreme Court hearing, the CAQM on Monday announced relaxations under the GRAP and eased Clause 11 of Stage-III and Clauses 5 and 8 of Stage-IV, allowing educational institutions to operate classes in a “hybrid” format and students to attend either in person or online. The option for online education, wherever feasible, will be made available to students and their guardians in Delhi, Gurugram, Faridabad, Ghaziabad, and Gautam Buddh Nagar (Noida).
  • SC raps Delhi govt over GRAP 4 curbs: Last Sunday, November 17, the air quality in Delhi reached hazardous levels, with AQI surpassing 450 for the first time this season, prompting the implementation of GRAP 4, which the Supreme Court on Monday said is not being done properly by the city government. The GRAP Stage 4 encompasses an 8-point action plan, including banning the entry of non-essential truck traffic into Delhi, except for trucks carrying essential commodities or providing essential services.
  • Delhi weather forecast: On Monday, the daytime temperature was recorded at 25.8 degrees Celsius, 0.9 notches below the seasonal average, as per the India Meteorological Department (IMD), which predicted forecast moderate fog for Tuesday, with the maximum and minimum temperatures likely to hover around 26 degrees Celsius and 12 degrees Celsius respectively.

After breaking the clothing rule, Carlsen leaves the World Rapid & Blitz event.

After breaking the clothing rule, Carlsen leaves the World Rapid & Blitz event.

World No 1 and defending champion refused to change after being fined for wearing jeans on Day 2 of the rapid event and chose to exit the tournament
Bengaluru: In a dramatic turn of events on Day 2 of the World Rapid and Blitz Tournament in New York, world No. 1 Magnus Carlsen decided to exit the tournament after a dress code breach. The defending champion arrived at the Wall Street venue on Friday dressed in a shirt, jacket, and a pair of jeans. According to Fide regulations for the event, players are prohibited from wearing jeans, shorts, t-shirts, sneakers, or baseball caps in the playing area. Carlsen was fined for the breach and asked to change. He refused to do the latter and as a result, he was not paired for round nine. He eventually decided not to play the whole tournament any further and leave New York instead. The blitz event starts on December 30.

“Today, Mr. Magnus Carlsen breached the dress code by wearing jeans, which are explicitly prohibited under long-standing regulations for this event. The chief arbiter informed Mr. Carlsen of the breach, issued a $200 fine, and requested that he change his attire. Unfortunately, Mr. Carlsen declined, and as a result, he was not paired for round nine. This decision was made impartially and applies equally to all players,” Fide said in its statement.

“Earlier in the day, another participant, Mr. Ian Nepomniachtchi, was also fined for breaching the dress code by wearing sports shoes. However, Mr. Nepomniachtchi complied, changed into approved attire, and continued to play in the tournament.”

Carlsen – who won the twin titles last year – had a far from good start to the tournament on Thursday – losing in one round, and escaping with draws from lost positions in two others to finish on a 50 percent score.

“Obviously this has not been the best tournament for me. Yesterday (Thursday) was a difficult day,” Carlsen told Take Take Take, “I lost one game, could have lost a couple more and generally I wasn’t playing well…was a bit out of control. Honestly, I had a good sleep and a lunch meeting before I came here and barely had time to go to the room and change so I put on a shirt and jacket. Honestly, I didn’t even think about the jeans. I don’t remember if it was after the first or second game…that I got fined and was given a warning that I would not be paired if I did not go change my clothes. I said I’ll change tomorrow if that’s okay, they said no, you have to change now. At that point it became a matter of principle for me, so here we are.”

He hinted at acrimony with Fide over Freestyle Chess, a chess960 event backed by German entrepreneur Jan Buettner. which he has been promoting and playing.

“There was this whole thing where Fide was actively going after players to get them not to sign with Freestyle, basically threatening them that they wouldn’t be able to play the World Championship cycle if they played in Freestyle. So honestly my patience with them was not very big to begin with. It’s okay… they can enforce their rules, it’s fine by me and my response then is – ‘I’m out, f**k you.’

“Honestly, I’m too old at this point to care too much. I guess it goes both ways and no one wants to back down. This is where we are…it’s fine by me. Probably I’ll head off to somewhere where the weather is a bit nicer than here.”
