Delhi: After briefly entering the severe category on Thursday, the air quality is extremely poor.

Even though forecasts indicated no significant change in meteorological conditions over the weekend, Delhi's air quality improved to the very poor category on Friday morning after briefly entering the severe zone on Thursday. During the day, wind speeds were predicted to reach five to six km/h, and the quality of the air was expected to stay extremely low. During the day, five to six km/h winds are expected in the Capital, and the extremely poor air quality is expected to persist.

At noon on Friday, the 24-hour average Air Quality Index (AQI) was 378 (very poor). On Thursday, the air quality index was 398 (very poor) at 4 p.m., and by 7 p.m., it had deteriorated to 401 (severe).

On Friday, the minimum temperature of 13.3°C was three degrees higher than average. It was Thursday, 12.6°C. It was expected that the wind would continue to be easterly on Friday and then shift to the northwest on Saturday. By Sunday, the minimum temperature was predicted to fall to 11°C. The high will remain at about 25°C until Sunday.

In November, Delhi experienced nine days with extreme air quality, with the AQI exceeding 400. Additionally, it noted nine more days with an AQI between 390 and 400 that was close to being severe. 18 near-severe or severe air days were reported in the Capital in November, the most since 13 such days were reported in November 2021 and 11 in November 2016.

The Commission for Air Quality Management (CAQM) reported on Thursday that Delhi experienced an average wind speed of four km/h in November, which is comparatively low. There were extended periods of calm winds. Ten kilometres per hour on average is an effective wind speed for dispersing pollutants.

November saw far fewer paddy farm fires in Punjab and Haryana than it had in the previous three years, according to CAQM. It claimed that extremely unfavourable weather and climatic conditions greatly increased Delhi's PM2.5 load. "This year's Deepawali festival fell during the height of the paddy harvesting season in Punjab and Haryana, exacerbating the air pollution..."

It stated that, compared to 49,922 last year, Punjab recorded 36,663 farm fires through November 30. With 2,303 fires reported this year, Haryana reported 3,661 last year.

In November, Delhi's 24-hour average AQI was 373. It was 376 in November 2021 and 321 in November of last year. According to CAQM, the year was cleaner than prior years when the average AQI for the entire year was examined.

Delhi AQI: Air quality is currently "bad" with a reading of 266; More information here

Delhi AQI: The System of Air Quality and Weather Forecasting and Research rated the air quality in the capital as "bad" on Saturday morning, with an AQI of 266. (SAFAR-India).

At 7:01 a.m., Lodhi Road's AQI reported at 211, which is considered to be a "bad" level, while the Pusa Road area's AQI was 193, which is considered to be a "moderate" level.

Similar to this, Gurugram's AQI was 162, which is considered to be "moderate." However, the AQI rose to 286 at the Delhi Airport (T3).

Around Delhi University, the air quality was recorded at 331, which is considered to be "extremely poor." The AQI in Noida (UP) was 283, which likewise put it in the "bad" quality zone.

An AQI of 201 at Ayanagar indicated "bad" air quality, while an AQI of 179 in Mathura Road indicated "moderate" air quality. The AQI for the vicinity of IIT Delhi was 215. Dhirpur recorded an AQI of 329, which is considered to be "extremely poor" for air quality.

The AQI is a tool made to make it easier to explain the public's air quality needs by utilising simple categories. Good, Satisfactory, Moderately Polluted, Poor, Extremely Poor, and Severe are the six AQI classifications. Based on the environmental air pollution concentration levels and their possible health effects, or "health breakpoints," these groups are categorised.

The AQI scale classifies air quality as "excellent" between 0 and 50, "acceptable" between 51 and 100, "moderate" between 101 and 200, "poor" between 201 and 300, "extremely poor" between 301 and 400, and "severe" between 401 and 450. When the AQI exceeds 450, the word "severe" is used.

On October 9, AAP Chief Spokesperson Priyanka Kakkar stated at a press conference, "Delhi's air quality continued to improve by 8% in 2022. Its improvement has increased by 31% as of 2023. The year 2023 will have the finest air quality in Delhi over the past eight years, excluding the COVID period."

Authorities in the National Capital Region were earlier urged to enact a ban on coal usage in hotels and restaurants by the National Air Quality Committee. As Delhi's air quality deteriorated to "bad," they were also instructed to impose sanctions on businesses and thermal power plants that contribute to pollution.

This action was taken as a part of the government's pollution management policy, known as the "Graded Response Action Plan" (GRAP), which was implemented in the Delhi-NCR region to combat air pollution issues during the winter.
