“…The instrument is a smaller lightweight version of the detector described in Schiff et al (1986) and has been fully described in Pisano et al (1996). It will only be discussed briefly here.…”

Abstract-A series of vertical profiles of temperature, relative humidity, N0 2 and 0, were determined in lhe Lower Fraser Valley, British Columbia, as part oClhe PACIFIC '93 field study. Data from one day show very slructured vertical distributions of all parameters in the morning, as expected from the limited vertical mixing under the nocturnal inversion. N0 2 concentrations of 20ppbv were observed 300 m above the surface, while the surface concentrations were -2 ppbv. Ozone and nitrogen oxide chemislry were observed at all altitudes throughout the PBL. Titration of 0, by NO to produce N0 2 was observed in layers above the ground, under the influence of the NBL. An increase in odd oxygen lhroughout lhe PBL, during the morning and early afternoon, shows "smog chemistry" is occurring even though the groundbased 0J measurements suggest this day was not particularly chemically active. However, once the NBL has dissipated, the ground-based measurements seem representative of lhe entire PBL.

“…The heterophase chemiluminescent method for measuring nitrogen oxides was developed as an alternative [4][5][6]. This method is based on measuring the chemiluminescent radiation in a reaction between a luminol solution deposited on a cloth substrate and NO 2 molecules.…”

We have developed and produced a small and inexpensive balloon-type instrument for tropospheric and stratospheric measurements of the content of nitrogen dioxide in the atmosphere, the NaDA. The instrument utilizes the reaction of liquid luminol with NO 2 , which results in the emission of light in the visible spectral region, and can operate under both tropospheric and stratospheric conditions. The range of measured concentrations is ~0.1-50 ppbv; the instrument's sensitivity is ~26000 pulses/s per 1 ppbv of NO 2 at atmospheric pressure and its mass is ~1 kg. Field tests of the instrument have been performed. A height profile of the NO 2 distribution in the atmosphere was obtained.

“…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.…”

“…This technique has been used in earlier attempts to make a light-weight instrument which can be launched with a balloon. Hasinoff (1997) used an NO 2 sonde, as described by Pisano et al (1996), in a field study at Kejimkujik National Park in Nova Scotia in 1996. The instrument weighs 1195 kg, and uses the luminol-NO 2 reaction.…”

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 .
