An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', then 401 and between 500 is considered 'severe'.

AQI indicates 'very poor' air quality due to low mixing (ventilation) throughout the day. Moderate wind speed and low boundary layer height (typical of winter) is going to keep AQI in 'very poor' for next two days. An improvement is expected due to western disturbance from December 24 onwards, it said in a bulletin. /IANS
