| description | <p>An instrument based on 20 m open-path incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) was established at the Jülich SAPHIR chamber in spring 2011. The setup was optimized for the detection of HONO and NO<span class="inline-formula"><sub>2</sub></span> in the near-UV region 352–386 nm, utilizing a bright hot-spot Xe-arc lamp and a UV-enhanced charge-coupled device (CCD) detector. A
2<span class="inline-formula"><i>σ</i></span> detection limit of 26 pptv for HONO and 76 pptv for NO<span class="inline-formula"><sub>2</sub></span> was
achieved for an integration time of 1 min. Methacrolein (MACR) was also
detected at mixing ratios below 5 ppbv with an estimated 2<span class="inline-formula"><i>σ</i></span>
detection limit of 340 pptv for the same integration time. The IBBCEAS
instrument's performance for HONO and NO<span class="inline-formula"><sub>2</sub></span> detection was compared to
that of extractive wet techniques, long-path absorption photometry (LOPAP),
and chemiluminescence spectrometry (CLS) <span class="inline-formula">NO<sub><i>x</i></sub></span> detection, respectively.
For the combined data sets an overall good agreement for both trend and
absolute mixing ratios was observed between IBBCEAS and these established
