title: The Aeroflex: a bicycle for mobile air quality measurements.
abstract: Fixed air quality stations have limitations when used to assess  people's real life exposure to air pollutants. Their spatial coverage is  too limited to capture the spatial variability in, e.g., an urban or  industrial environment. Complementary mobile air quality measurements  can be used as an additional tool to fill this void. In this publication  we present the Aeroflex, a bicycle for mobile air quality monitoring.  The Aeroflex is equipped with compact air quality measurement devices to  monitor ultrafine particle number counts, particulate mass and black  carbon concentrations at a high resolution (up to 1 second). Each  measurement is automatically linked to its geographical location and  time of acquisition using GPS and Internet time. Furthermore, the  Aeroflex is equipped with automated data transmission, data  pre-processing and data visualization. The Aeroflex is designed with  adaptability, reliability and user friendliness in mind. Over the past  years, the Aeroflex has been successfully used for high resolution air  quality mapping, exposure assessment and hot spot identification.
