The We For News reported, Delhi-NCR region woke up to a hazy Monday morning with a marginally improved Air Quality Index (AQI) of 368 (very poor) at 9 a.m. after the national capital recorded three days of “severe” air category.

India Meteorological Department (IMD) data showed, the maximum temperature for the day has been recorded at 14 Degrees Celsius and minimum at 29 Degrees Celsius.

Relative humidity at 8.30 a.m. was recorded at 85 per cent.

According to the System of Air Quality and Weather Forecasting And Research (SAFAR), the severe category was because of the large influx of stubble related pollutants which appears to be due to much higher effective fire count observed than that assumed in the SAFAR model for forecasting.

SAFAR had further predicted that an improved AQI by November 7 due to favourable wind speed and direction and significantly high fire counts since Saturday.

The stubble fire related contribution simulated by the SAFAR model has risen to the highest level of 48 per cent of this season with SAFAR effective fire count touching despite moderate wind speed with fire count touching 4,189.

AQI is forecasted to improve but stay in the high end of very poor to severe category for November 9 as well.

The level of PM 2.5 and PM 10 pollutants in the capital’s air on November 8 has been pegged at 208 and 338, respectively.
