AEROMET

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 (10 2 to 10 6 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... To develop reproducible reference methods for PM 10 and PM 2.5, including the design and building of a demonstration aerosol chamber system - for calibrating PM 10 and PM 2.5 instruments using representative generated aerosols and to achieve target uncertainties below 15 %.
