According to the Central Pollution Control Board, the hourly Air Quality Index (AQI) was 153 at 7 am. 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’.

On Wednesday, monitoring agency System of Air Quality and Weather Forecasting And Research (Safar) said AQI indicated “upper end of moderate” air quality with PM10 as primary pollutant. “Dust (size > 2.5 micrometer) contributes ~ 76% to PM10.”

It said the peak wind speed is likely to be ~ 24 km/h and cause moderate dispersion for the next three days and AQI is likely to be within moderate or lower end of poor. “High temperature (> 41°C) and mixing layer height (~ 3-4 km) maintains strong ventilation by convection improving air quality.”
