Short summary
A new incoherent broadband cavity-enhanced absorption spectrometer for ambient NO3 and N2O5 detection is developed. This new instrument is featured with a mechanically aligned non-adjustable optical mounting system. Fast setup and stable running of this N2O5 spectrometer were successfully achieved during recent field campaigns in China due to this new feature. In addition, a dynamic reference spectrum is used for the CEAS type of instrument by NO titration for the first time.
