  • Uncertainty of NO2 measurements by chemiluminescence; a case study at the JRC AIRMON station and discussion of the quality objective of the NO2 European directive

Abstract

The European Directive 99/30/EC gives a data quality objective of 15 % for the accuracy of NO2 continuous monitoring. This paper describes the implementation of the Guide for the expression of Uncertainty of Measurement (GUM) method and gives an example of uncertainty calculation taking onto account all components of uncertainty. The relative influence of all possible sources to the uncertainty budget is evaluated and recommendation about which ones should be monitored is given. Finally, the ability of the chemiluminescence method to meet the data quality objective of the European Directive is discussed.
