The national capital\u2019s air quality on Friday morning touched the severe category after being in the very poor category for six consecutive days until Thursday. Reports said that Delhi\u2019s air quality index (AQI) at 7.05 am on Friday stood at 401 (severe).<\/p>\n\n\n\n
Notably, this is a deviation from the forecasts on Thursday, which had indicated that Delhi\u2019s Air Quality Index was expected to remain very poor on Friday, and possibly touching severe only on Saturday. The Early Warning System (EWS) for Delhi, which is a forecasting model used by CAQM in the National Capital Region, predicted that the national capital\u2019s air quality is likely to remain very poor again on Sunday. <\/p>\n\n\n\n
Earlier on Thursday, the AQI had marginally improved in comparison to Wednesday as dipping temperature and calm winds at night provided no respite to the capital. The capital\u2019s 24-hour average air quality index (AQI) was recorded at 390 (very poor), according to Central Pollution Control Board\u2019s national bulletin at 4 pm on Thursday, with it recorded at 395 (very poor) at the same time on Wednesday.<\/p>\n\n\n\n
Reportedly, an AQI of 51 to 100 is classified as satisfactory, between 101 and 200 is classified as moderate, between 201 and 300 is classified as poor, between 301 and 400 is classified as very poor and more than 400 is severe by the Central Pollution Control Board (CPCB).<\/p>\n\n\n\n
Though the national capital has registered eight severe air quality days so far this month, when the AQI has been over 400, it has been on the brink of severe 390 or higher on another six days, making it 14 such days with an AQI of 390 or higher. Notably, this is the highest tally of such days in November in the last eight years, with the previous high of 13 such days coming in November 2021.<\/p>\n\n\n\n
In 2022, Delhi recorded three such days, nine in 2020, eight each in 2019 and 2018, seven in 2017, 11 in 2016 and seven in 2015.<\/p>\n","protected":false},"excerpt":{"rendered":"
