| Zusammenfassung |
| NO2 concentrations were measured by various instruments during the NO3Comp campaign
at the atmosphere simulation chamber SAPHIR at Forschungszentrum Jülich, Germany,
in June 2007. Analytical methods included photolytic conversion with chemiluminescence (PC-CLD),
broadband cavity ring-down spectroscopy (BBCRDS), pulsed cavity ring-down spectroscopy
(CRDS), incoherent broadband cavity-enhanced absorption spectroscopy (IBB\-CEAS), and
laser-induced fluorescence (LIF). All broadband absorption spectrometers were optimized for
the detection of the main target species of the campaign, NO3, but were also capable
of detecting NO2 simultaneously with reduced sensitivity. NO2 mixing ratios
in the chamber were within a range characteristic of polluted, urban conditions, with
a maximum mixing ratio of approximately 75 ppbv. The overall agreement between
measurements of all instruments was excellent. Linear fits of the combined data sets
resulted in slopes that differ from unity only within the stated uncertainty of each
instrument. Possible interferences from species such as water vapor and ozone were
negligible under the experimental conditions. |
