FAQ
- What do min, max, and average mean here?
- These are pollutant sub-index values for the monitoring station as held in DeshSeva. They are not the same as a single composite National AQI headline number; readings are per pollutant (e.g. PM2.5, PM10).
- Where does this data come from?
- DeshSeva can sync snapshots into our database on a schedule; otherwise this page may fetch live readings depending on setup.
- Why do some values show NA?
- When a pollutant is not reported or not available for that interval, the source may publish NA for min, max, or average.
