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.
