According to the System of Air Quality and Weather Forecasting And Research (SAFAR), the city recorded an AQI of 206 and remained in the poor category. The temperature has been recorded at 33°C and the humidity at 62 percent.

Meanwhile, the sudden drop in temperature (17°C) witnessed last week was due to a cold wave, after which the minimum temperature of the city sprang back to 23 °C this week.

However, the minimum temperature witnessed a rise again this week due to a weather system in Tamil Nadu, and continued to hover between 21°C to 23°C.

A layer of smog prevailed over the national capital on Sunday morning as the overall Air Quality Index (AQI) was recorded at 315, according to the System of Air Quality and Weather Forecasting and Research (SAFAR). Whereas AQI of Pune and Ahmedabad were 143, and 119 respectively. Air Quality Index is a tool for effective communication of air quality status to people in terms, which are easy to understand.

It transforms complex air quality data of various pollutants into a single number (index value), nomenclature and colour. The Air Quality Index from 0 to 100 is considered as good, while from 100 to 200 it is moderate, from 200 to 300 it is poor, and from 300 to 400 it is said to be very poor and from 400 to 500 or above it is considered as severe. Amid continuing poor air quality, the Sub-Committee for invoking actions under the Graded Response Action Plan (GRAP) held a meeting on November 18 to review the progress of the actions implemented under Stage II along with Stage I of the GRAP in the entire NCR.

As per the dynamic model and weather/ meteorological forecast provided by IMD/ IITM, the overall air quality is likely to fluctuate largely between ‘Poor’ to the lower end of the ‘Very Poor’ categories in the next few days. The predominant surface wind is predicted to be coming from the North/North-West direction in Delhi, the Ministry of Environment, Forest and Climate Change said. The Sub-Committee of the Commission is closely watching the situation and will review the air quality scenario accordingly.
