abstract = {Nitrogen dioxide is a well-known pollutant which has effect on
human health, with pulmonary problems, and on the atmosphere
chemistry, where it is responsible for acid rains for example.
Consequently, current European standards impose very low NO2
emission thresholds in exhaust gases. Thus, there is a need
for novel sensors able to monitor small NO2 concentrations for
real time adjustments of engines performances. In this
perspective, absorption spectroscopy is a method of great
interest as it has been largely used in the past to measure
NO2 concentration in air atmosphere. Such measurements require
the knowledge of the NO2 absorption cross-sections. As the
atmosphere is a \'ecold\'e environment, these data is only known
up to 25°C. The first purpose of this study is then, to
measure the absorption cross-sections of NO2 at higher
temperatures, i.e. up to 150°C. Then, based on these results,
absorption measurements were performed on hot gas mixtures
containing very small concentrations of NO2 (<5ppm). A
resolution close to one part per million was observed.}
