We measure the air quality in Otaniemi near Ring I in Espoo, in 2020. The results of the station describe the air quality in busy district in Espoo.
At this monitoring station we measure, among others, the concentrations of nitrogen dioxide, street dust and fine 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 colour), people sensitive to air pollutants may show some symptoms. The graph shows the air quality indices from the last 12 hours (unverified hourly values).
