On Saturday, the AQI in Delhi remained in the 'very poor' category with the Air Quality Index (AQI) recorded at 347.O. System of Air Quality and Weather Forecasting and Research (SAFAR), said that some locations entered ''severe'' zone but that will be short lived as winds are expected to increase slightly. It said the air quality could improve on October 26. "The overall Delhi's Air Quality Index (AQI) is in the very poor category with few Delhi locations entering at higher zone but that will be short lived. This is mainly because the extremely calm local surface winds which were prevailing yesterday are likely to increase slightly and may further pick-up by Oct 26," SAFAR said.
On Friday, 10 monitoring stations in Delhi entered the 'severe' zone, according to the AQI monitoring mobile application SAMEER, developed by the Central Pollution Control Board (CPCB). The air quality index (AQI) on Friday was recorded 366 while it was 302 on the previous day.
An AQI between 0 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'.
