Ring III Varisto

We measure the air quality near Ring III in Varisto Vantaa, in 2020. The results of the station describe the air quality near busy motorways in Vantaa.

At this monitoring station we measure, among others, the concentrations of nitrogen dioxide, fine particles and inhalable particles.

​​The results are presented through an air quality index that correlates the concentrations to their health effects. The index varies from good to very poor. When the air quality is poor (red colou​r), people sensitive to air pollutants may show some symptoms. The graph shows the air quality indexes from the last 12 hours (unverified hourly values).​
