New Delhi: The air quality in the national capital again deteriorated on Friday, slipping into ‘very poor’ category, according to the System of Air Quality and Weather Forecasting And Research (SAFAR).
The overall Air Quality Index (AQI) on Delhi was recorded this morning at 308. The concentrations of PM 2.5 and PM 10 stood at 130 in the ‘very poor’ and 237 in the ‘moderate’ category respectively.
“AQI today indicates ‘Very Poor’ air quality. Prevailing cold wave conditions in the northwest region of Delhi and winds blowing from the west/northwest direction affect weather in Delhi. However, minimum and maximum temperatures show a tendency to increase slightly for the next 3 days (December 31, January 1 and January 2). Consistently high wind speeds are likely for the next three days. Mixing layer height continues to be 1.0 – 1.5 km,” SAFAR said in its bulletin.
According to the SAFAR bulletin, New Year celebrations on December 31 night may increase emissions and worsen the air quality, but the net effect is likely to keep AQI within ‘very poor’ or ‘higher end of very poor’ for the next three days.
While the air quality of Noida remains in the ‘very poor’ category with AQI at 304 and air quality of Gurugram is in ‘poor’ category with AQI at 252.
