In India, System of Air High quality Climate Forecasting and Analysis (SAFAR) and Central Air pollution Management Board (CPCB) categorise AQIs between 101-200 as ‘reasonable’, 201-300 as ‘poor’, 301-400 as ‘very poor’, and people above 400 as ‘extreme’.

SAFAR forecasts that the AQI might stay within the reasonable class for the subsequent two days. Suppose the nationwide capital area receives substantial rainfall by Friday as forecast. In that case, the air pollution load is more likely to drop considerably, and the air high quality might enhance to passable ranges throughout Delhi 0ver the weekend.
