Delhites woke up to a thick layer of smog blanketing the national capital on Tuesday as the overall air quality of Delhi remained in the ‘very poor’ category.
According to the System of Air Quality and Weather Forecasting and Research (SAFAR), Deli's AQI stood at 323 at 5.17 am on Tuesday.
The Air quality in Delhi and its adjacent areas aggravated again overnight following a marginal improvement a day ago, with forecasts suggesting that a major relief is unlikely in the coming days.

Moreover, all government-aided and private schools reopened on Monday after GRAP Stage-IV curbs were revoked. The pollution control body, however, said all other curbs under stages I, II and III of GRAP, including a ban on non-essential construction work, mining, stone crushers and diesel generators will continue.
