The meanings above are ours, in short. The publisher's own advice for each band: India's Central Pollution Control Board (CPCB).
Each scale here is its PM2.5 part only. Official indexes take the worst of several pollutants, so a city's official number can be higher. The scales are defined on 24-hour means (AQHI+ on hourly ones); how we use them.
