What is the AQI?
The Air Quality Index turns complex pollution data into one number people can understand.
Under CPCB classification: 0–50 good, 51–100 satisfactory, 101–200 moderate, 201–300 poor, 301–400 very poor, 401–500 severe.
In the Indo-Gangetic plain, winter cold, low wind, farm fires and firecrackers often trap smoke near the ground.
Delhi-NCR uses the Graded Response Action Plan (GRAP); UP cities follow State and CPCB guidance.
