Benefits of low-cost air quality stations

New opportunities to conduct monitoring in locations and situations where traditional systems are not feasible solutions.

Higher spatial resolution of measurements.

Better understanding of local air quality concerns.

Enriched engagement for air quality communities and stakeholders.

Preliminary Results from our low-cost air quality station

Empa’s Laboratory for Air Pollution and Environmental Technology have co-located eight low-cost air quality stations (45 sensors) with traditional road-side instruments in Zurich,  Switzerland.  The initial results look promising.
