Quality assessment of ambient NO, NO(2) and SO(2) measurements in European monitoring networks
Quality control of calibration and maintenance in 36 stations within European monitoring networks has been assessed with a mobile laboratory equipped with a prototype test atmosphere (SO(2)-NO-NO(2)) generator. A mixture was injected into the sampling line inlet and analysed by the station analyser as well as reference instruments within the mobile laboratory connected to either end of the sampling line. Measurement accuracy was assessed by calculating the deviation of the data with respect to the reference. Quality checks were carried out for the global routine measurement, the station's analyser readout and station's sampling line separately.
