资源简介：
Type of analyzer :The IMT Nox analyzer is a T200UP from Aerodyne.
Data averaging :Native data were acquired each minute.
Blank : A blank from the measurement system was subtracted. Zero air was generated using a synthetic air cylinder 5.0. The frequency of the blank is each 1h45 and last 15 minutes.
Due to the lack of purity of the blank an offset at 21 ppt had been added. The negatives values for NO seem to indicate an overestimated value of the zero of the analyser, which is estimated to an hundred of ppt.
Calibration :The calibration is done with a standard of 200ppb of NO2
Nox corrections : The reaction between NO and ozone had been taken in account and had lead to a correction of raw data of Nox. This correction was applied on NO and NO2 values only if the NO value was above the LOD at 30 ppt.
Incertainties :
The incertaintes are calculated at 1sigma. The precision is reported with Nox values. The accuracy is 3.2% for NO and 5.9% for NO2.
