Assessment of urban air quality with mobile measurements using a bicycle (MOBAIR)

The ambient air quality is a well-known problem for big cities with dense population and high traffic volume. The air quality is usually monitored with measurement stations. However, limited spatial resolution and restricted possibility of mapping spatial distribution of air pollutants is a drawback. To provide high spatial and temporal resolution, mobile measurements are necessary. This study aims to investigate the air quality of an urban city by performing mobile measurements using bicycle (MOBAIR) equipped with devices to measure air pollutants such as nitrogen oxides, ozone, particulate matter, ultra fine particles and black carbon as well as meteorological parameters such as air temperature, relative humidity, air pressure, wind speed, wind direction and solar radiation. The measurement route covered a big part of the city with high traffic roads as well as side roads and park in order to obtain a broader picture and to identify the contribution of traffic to the air quality.
