A quantum cascade laser based absorptionspectrometer for continuous and direct measurements of NO and NO2 wasemployed at the high-altitude monitoring site Jungfraujoch (3580 m a.s.l., Switzerland) during a three-month campaignin spring/summer 2012. The total reactive nitrogen, NOy, was also measured in the form of NO after conversion ona gold catalyst. The aim was to assess the suitability of the instrument for long-term monitoring of the main reactive nitrogenspecies under predominantly free tropospheric air conditions. A precision (1σ) of 10 and 3 ppt for NOand NO2 was achieved under field conditions after 180 s averaging time. The linear dynamic range of theinstrument has been verified for both species from the detection limit up to 45 ppb. The spectrometer shareda common sampling inlet with a chemiluminescence-based analyzer. The comparison of the time series shows excellent agreementbetween the two techniques and demonstrates the adequacy of the laser spectroscopic approach for this kind of demandingenvironmental applications
