How often the air is above the limit
For every official monitoring station in BiH: on how many days or hours a year the air was above the legal limit, and how many are allowed. Only measured values count.

A day runs from midnight to midnight local time; a daily average needs at least 18 of 24 hours measured. Model estimates do not count.
≥ means at least: the station is missing more than a tenth of the days or hours, so it ranks lower than it would with complete readings.
In Republika Srpska the hourly limit for NO₂ is 150 µg/m³; for stations in the RS we count the hours above 150.
Grey at the end: stations with 0 but too few readings, and, marked ³, stations whose unverified hourly values jump unusually strongly. We compare neither with the allowed number.
