Abstract. An incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) technique has been developed for in situ monitoring of NO3 radicals at the ppt level in the CSA simulation chamber (at LISA). The technique couples an incoherent broadband light source centered at 662 nm with a high finesse optical cavity made of two highly reflecting mirrors. The optical cavity which has an effective length of 82 cm allows for up to 3 km of effective absorption and a high sensitivity for NO3 detection (up to 6 ppt for an integration time of 10 seconds). This technique also allows NO2 monitoring (up to 9 ppb for an integration time of 10 seconds). Here, we present the experimental setup as well as tests for its characterization and validation. The validation tests include an intercomparison with another independent technique (FTIR) and the absolute rate determination for the reaction trans-2-butene + NO3 which is already well documented in the literature. The value of (4.13 ± 0.45) x 10-13 cm3 molecule-1 s-1 has been found, which is in good agreement with previous determinations. From these experiments, optimal operation conditions are proposed. The technique is now fully operational and can be used to determine rate constants for fast reactions involving complex volatile organic compounds (with rate constants up to 10-10 cm3 molecule-1 s-1).
