“…For example, the processes may convert up to 92 % of peroxyacetyl nitrate (PAN) and 98 % of nitric acid (HNO 3 ) into NO (Winer et al, 1974;Grosjean and Harrison, 1985). The luminol technique is known for significant interferences with O 3 and PAN (25 %) especially at low NO 2 concentrations (Drummond et al, 1989;Kelly et al, 1990). Such interferences were found to be negligible with photolytic converters (Fehsenfeld et al, 1990;Ryerson et al, 2000).…”

Abstract. The nitrogen dioxide (NO 2 ) exchange between the atmosphere and needles of Picea abies L. (Norway Spruce) was studied under uncontrolled field conditions using a dynamic chamber system. This system allows measurements of the flux density of the reactive NO-NO 2 -O 3 triad and additionally of the non-reactive trace gases CO 2 and H 2 O. For the NO 2 detection a highly NO 2 specific blue light converter was used, which was coupled to chemiluminescence detection of the photolysis product NO. This NO 2 converter excludes known interferences with other nitrogen compounds, which occur by using more unspecific NO 2 converters. Photo-chemical reactions of NO, NO 2 , and O 3 inside the dynamic chamber were considered for the determination of NO 2 flux densities, NO 2 deposition velocities, as well as NO 2 compensation point concentrations. The calculations are based on a bi-variate weighted linear regression analysis (y-and x-errors considered). The NO 2 deposition velocities for spruce, based on projected needle area, ranged between 0.07 and 0.42 mm s −1 . The calculated NO 2 compensation point concentrations ranged from 2.4 ± 9.63 to 29.0 ± 16.30 nmol m −3 (0.05-0.65 ppb) but the compensation point concentrations were all not significant in terms of compensation point concentration is unequal to zero. These data challenge the existence of a NO 2 compensation point concentration for spruce. Our study resulted in lower values of NO 2 gas exchange flux densities, NO 2 deposition velocities and NO 2 compensation point concentrations in comparison to most previous studies. It is essential to use a more specific NO 2 analyzer than used in previous studies and to consider photo-chemical reactions between NO, NO 2 , and O 3 inside the chamber.

“…Mikuška et al (2000) shows that the nonlinearity depends on the chemical composition of the luminol solution, while Pisano et al (1996) claim that the nonlinearity differs from instrument to instrument. Kelly et al (1990) reported a change of sensitivity of his detector over time, and hints at a possible dependence on the age of the chemicals used. The reported nonlinearity's would, however, lead to corrections of less than 1 ppbv.…”

“…In situ profile measurements have been performed in a number of aircraft campaigns (e.g., Boersma et al, 2008;Kelly et al, 1990). A disadvantage of aircraft measurements is, apart from their relatively high cost, that the lower few hundred metres of the atmosphere, which contain a significant part of the tropospheric NO 2 , are difficult to reach.…”

The development of a nitrogen dioxide sonde

Abstract.A growing number of space-borne instruments measures nitrogen dioxide (NO 2 ) concentrations in the troposphere, but validation of these instruments is hampered by the lack of ground-based and in situ profile measurements.The Royal Netherlands Meteorological Institute (KNMI) has developed a working NO 2 sonde. The sonde is attached to a small meteorological balloon and measures a tropospheric NO 2 profile. The NO 2 sonde has a vertical resolution of 5 m and a measurement range between 1 and 100 ppbv. The instrument is light in weight (0.7 kg), cheap (disposable), energy efficient and not harmful to the environment or the person who finds the package after use. The sonde uses the chemiluminescent reaction of NO 2 in an aqueous luminol solution. The NO 2 -luminol reaction produces faint blue/purple light (at about 425 nm), which is detected by an array of silicon photodiodes. The luminol solution is optimised to be specific to NO 2 .

“…Kelly et al 40 evaluated the performance of the Luminox, model LMA-3, and noted that, to obtain accurate measurements of NO 2 at low concentrations, the readings must be corrected for zero offset, nonlinearity, and O 3 and PAN interferences, in that order. Using the Luminol II solution, they noted a linear response greater than 2 ppbv with a positive response offset of 1.3 ppbv.…”

The capping of stationary source emissions of NO x in 22 states and the District of Columbia is federally mandated by the NO x SIP Call legislation with the intended purpose of reducing downwind O 3 concentrations. Monitors for NO, NO 2 , and the reactive oxides of nitrogen into which these two compounds are converted will record data to evaluate air quality model (AQM) predictions. Guidelines for testing these models indicate the need for semicontinuous measurements as close to real time as possible but no less frequently than once per hour. The measurement uncertainty required for AQM testing must be less than ±20% (±10% for NO 2 ) at mixing ratios of 1 ppbv and higher for NO, individual NO z component compounds, and NO y . This article is a review and discussion of different monitoring methods, some currently used in research and others used for routine monitoring. The performance of these methods is compared with the monitoring guidelines. Recommendations for advancing speciated and total NO y monitoring technology and a listing of demonstrated monitoring approaches are also presented.
