New Delhi, Nov 29 (IANS): After witnessing few of the worst air quality days in November, the national capital on Friday saw a drastic improvement in the pollution levels as the AQI came down to double digits at the 'satisfactory' category.
According to the Centre-run System of Air Quality and Weather Forecasting (SAFAR), the overall air quality index (AQI) was recorded at 97.
"Under the influence of Western Disturbance fairly widespread precipitation recorded in consecutive days which led to the improvement in air quality," the SAFAR said.
