About this station
The Munich-Altperlach background monitoring station in Munich is operated by UBA (Umweltbundesamt) and reports under EEA Dataflow E1a as part of Germany's contribution to Directive 2008/50/EC. As an urban background station, readings here represent the ambient air across the city away from any direct emission source, the appropriate reference for population-weighted exposure estimation.
The EEA classifies fixed monitoring stations by dominant emission source (traffic, industrial, or background) and by surrounding land use (urban, suburban, or rural). Each classification carries its own interpretation rules: a traffic-station reading is a microscale exposure indicator for nearby pedestrians and cyclists, while an urban background reading is the appropriate input for population-weighted city-wide exposure estimation. Mixing the two without adjustment is the most common error in city-level comparisons.

Annual means smooth over daily and seasonal peaks. A traffic station's reading is not the city-wide average.
All concentrations in µg/m³, estimated by combining EEA Air Quality e-Reporting country-level data with this station's classification (station DEBY004), not an independent per-station reading. See our methodology for the exact derivation.
