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.

Below are example datasets
