The aim of this report was to evaluate and validate NO2B4 sensors of AlphaSense within laboratory and field tests under ambient/indoor air conditions corresponding to a specific micro-environment: traffic station, urban/suburban areas. This report presents the evaluation of the performances and determination of the laboratory and field measurement uncertainty of the sensor values, compared to uncertainties fixed by the Data Quality Objective (DQO) of the European Air Quality Directive for indicative method. Further, procedures for the calibration of sensors able to ensure full traceability of measurements of sensors to SI units are developed.
