NOx (mono-nitrogen oxide) chemiluminescence analyser data collected at Haley Clean Air Sector laboratory (CASLab), 2004-2005
NOx measurements were made, using a chemiluminescence analyser, between 2004 and 2005. This work was carried out at the Clean Air Sector Laboratory (CASLab) at Halley Station, Antarctica, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

|Quality:||See dataset header|
|Lineage:||Data frequency and averaging:
Mixing ratios are one minute averages of the 1 second frequency recorded data, timestamped at mid-point.
Data coverage and measurement duty cycle:
Missing data represent gaps when the instrument duty cycle is not on measure mode or during operational downtime
(powercuts, service/corrective maintenance).
The normal measurement duty cycle was as follows:
Detectors calibrations (twice daily, repeat time 13Hrs, staggered with artifact).
Detectors artifact determinations (twice daily, repeat time 13Hrs, staggered with calibrations).
Detector pre-chamber zeroing (1 minute every 10 to 15 minutes).
Data accuracy and error reporting:
Three errors are reported for each mean mixing ratio.
The random error is the 1 sigma standard error calculated for each mean mixing ratio, and represents the precision of the
measurement. It arises mainly from photon-counting statistics. This error will decrease with data averaging.
The systematic error is the propagation of all known uncertainties affecting the accuracy of the measurement (gas calibrant
concentration, linear interpolation of baseline, instrumental artifact correction). This error will not decrease with data
The overall uncertainty is the rms of the random and systematic errors.
