Delhi witnessed a significant improvement in the air quality on Wednesday morning.
According to the System of Air Quality and Weather Forecasting and Research (SAFAR), the overall Air Quality Index (AQI) in Delhi stood at 176 on Wednesday morning which was a major improvement from the previous day's AQI of 221.
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", and 401 and 500 "severe".
