General description A data collection experiment using machines and a measuring point to collect microparticle concentrations during street cleaning to assess air quality. PM10, PM2.5 and PM1 concentrations from...

Monthly and annual averages of air pollution, concentrations comparable to norms, maximum hour values and data on the temporal representativeness of measurements in Uusimaa.

Map level shows real-time air quality as an index of air quality in the permanent and mobile measurement stations of the Helsinki Region Environmental Services (HSY). The measurement result is updated hourly. HSY...

Air quality measurements which are collected using devices installed on trams from Helsinki. Three sensor sets have been moving on the streets of Helsinki, while one has been constantly at Helsinki Environmental...

The dataset shows the areas where the annual limit value for nitrogen dioxide (40 µg/m3) has exceeded or has been in danger of exceeding. In 2022 it was estimated that the annual limit value of nitrogen dioxide will...

Monitoring site data includes permanent monitoring sites, mobile monitoring sites and passive samplers, as well as the annual average concentrations (μg/m3) of nitrogen dioxide (NO2) measured at these sites in...

Monthly and annual averages of air pollutants in the Helsinki metropolitan area, concentrations comparable to standards, maximum hourly values and data on the temporal representativeness of monitoring.

The material contains the air quality indices of HSY’s air quality monitoring sites on an hourly basis. The air quality index divides air quality into five different classes, from good to very poor. The index classes...
