Delhi AQI

New Delhi: Due to the low traffic after amid lockdown, air pollution in the national capital has slightly got down.
Delhi’s air quality remained in the ‘moderate’ category for the second consecutive day on Wednesday morning (April 15). The overall AQI stood at 110, according to the latest estimates updated by System of Air Quality and Weather Forecasting And Research (SAFAR).

Long-range dust transport from the dry arid western region is expected by Wednesday.

‘Satisfactory’ air in parts of Delhi

Meanwhile there were some areas in the national capital which recorded air quality in the ‘satisfactory’ category. These include Delhi University, Pusa Road, Mathura Road, IIT-Delhi and Indira Gandhi International Airport (Terminal-3) with an AQI of 57, 92, 91, 97 and 93 respectively.

According to SAFAR, AQI between the range of 51 and 100 is considered as ‘satisfactory’ or ‘very good’, 101-200 is ‘moderate’, 201-300 falls under the category of ‘poor’. While 300-400 is considered as ‘very poor’, levels between 401-500 fall under the ‘hazard.

SAFAR forecast

“Though the probability for any heavy dust storm is remote, long-range dust transport from the dry arid western region is expected by Wednesday. This can further deteriorate AQI towards the higher end of moderate to poor category (15th April). This impact is purely attributed to external natural factors linked to dust and independent of local emissions. Marginal improvement and moderate AQI is forecasted for 16th April. This impact is purely attributed to external natural dust and nothing to do with local emissions. The ratio of PM2.5 to PM10 has declined significantly confirming missing sources of fossil fuel emission,” SAFAR forecast said.

AQI in NCR 

The NCR too has enjoyed a spell of clean air after the lockdown on March 24. On Wednesday morning, Noida and Gurugram registered an AQI of 198 and 86 in the ‘moderate and ‘satisfactory’ category respectively.
