Short summary

We have developed a two-channel broadband cavity enhanced absorption spectrometer for field measurements of glyoxal, methylglyoxal, nitrous acid, nitrogen dioxide, and water. We have successfully deployed this instrument during two aircraft and two ground-based field campaigns. The demonstrated precision (2σ) for retrievals of CHOCHO, HONO, and NO₂ are 34, 350, and 80 parts per trillion (pptv) in 5 s, with accuracy of 5.8, 9.0 and 5.0 %.
