Harmonisation of air quality measurements in Europe (HAMAQ)

Project Description

The aim of the project is

  • to develop the methodology whereby internationally-accepted calibration gas standards can be produced and the concentration certified so as to promote widespread uniformity and accuracy of air quality measurements throughout Europe;
  • to demonstrate the equivalence of different 'primary' methods available in different member states for providing nationally traceable calibrations of air quality measurements of atmospheric pollutants (CO, NO, NO_2, SO_2 and C_6H_6) in order that these methods can be employed to certify stable gas calibration mixtures produced commercially;
  • to develop improved gas cylinder surface passivation treatments by means of the industrial partners, and to evaluate their effectiveness in order to provide more accurate, stable long lifetime calibration gas mixtures of CO, NO., Ned SO_2 and C_6H_6;
  • to provide technology transfer, in order to promote improved measurements in Member States where the air quality measurement infrastructure is not yet fully mature or is not yet of demonstrated accuracy.
