Aerosol metrology for atmospheric science and air quality

The overall aim of the project is to develop and demonstrate methods for traceability and calibration of different aerosol instruments capable of covering the environmentally relevant size range from several nm up to 10 µm and the regulatory relevant mass concentrations (0.1 µg/m³ to 1000 µg/m³) and number concentrations (102 to 106 particles per cm³). The traceability and calibration will consider the above metrics as well as mass concentration and chemistry of particle components. The project also aims to provide the necessary EU wide calibration infrastructure for aerosol instruments.
