New Delhi, Improvement has been seen in the air quality in the capital Delhi as soon as the weather turns. On Thursday, the level of pollution in the air has been measured in the moderate range by improving the quality. According to the System of Air Quality and Weather Forecasting and Research (SAFAR), the overall air quality index (AQI) in Delhi stood at 173 this morning. The level of air pollution in Delhi had come down from ‘very poor’ to ‘poor’ category in the past. The prevailing winds are also being considered as a major reason for the improvement in the air.
An air quality index from 0 to 100 is considered good, while 100 to 200 is moderate, 200 to 300 poor, 300 to 400 very poor, and 400 to 500 or above is considered severe. The improvement in Delhi’s air quality is also due to the decline in incidents of stubble burning in neighboring states. SAFAR said that the pollution caused by stubble burning in Delhi’s PM 2.5 has reduced to 3 percent. In view of the improvement in the overall air quality of Delhi-NCR observed in the last few days, the third phase of the Graded Response Action Plan (GRAP) has been canceled in the entire NCR.
However, actions under Phase I to Phase II of GRAP will continue to be in force and will be “implemented, monitored and reviewed by all concerned agencies across the NCR to ensure that the AQI levels do not fall further into the ‘severe’ category. Visibility has also been seen to improve to a great extent in Delhi due to the reduction of pollution.
