Short summary

We describe a new spectrometer for quantification of HONO and NO₂ in ambient air, called HODOR. The instrument uses an LED and two highly reflective mirrors to increase the effective optical absorption path to ~6 km. The accuracy of concentration retrievals was validated using parallel measurements by a single wavelength cavity ring-down spectrometer of laboratory-generated gas mixtures. The instrument's precision suffices for quantification of HONO and NO₂ in an urban environment.
