We measure the air quality in Leppävaara, nearby Shopping Centre Galleria. The results of the station describe the air quality in the Espoo areas with busy traffic.
At this monitoring station we measure, among others, the concentrations of nitrogen dioxide, particles of different sizes, and black carbon.
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 12 hours (unverified hourly values).
