Recital 16

(16) In order to ensure that the information collected on air pollution is sufficiently representative and comparable across the Union, it is important that standardised measurement techniques and common criteria for the number and location of sampling points are used for the assessment of ambient air quality. Techniques other than measurements can be used to assess ambient air quality and it is therefore necessary to define criteria for the use and required accuracy of such techniques.
