CPCB has classified an AQI between 0 and 50 is considered 'good', 51 to 100 'satisfactory', 101 to 200 'moderate', 201 to 300 'poor', 301 to 400 'very poor' and 401 to 500 'severe'.
However, the relief is expected to be short-lived, with air quality likely to worsen again in the coming days. Surface winds from the northwest, reaching 15–25 kmph during the day, helped disperse pollutants, revealing clear blue skies across Delhi NCR following the passage of a western disturbance over the Himalayas.
On the weather front, Delhi recorded a minimum temperature of 6.5 degrees Celsius, one notch below normal, and a relative humidity of 63 per cent, according to the India Meteorological Department.
Meanwhile, the Commission for Air Quality Management (CAQM) in Delhi-NCR lifted curbs imposed under Stage IV of the Graded Response Action Plan (GRAP) on Wednesday.
