Short summary
We report on the use of thermal dissociation cavity ring-down spectroscopy to detect NO2, peroxy nitrates and alkyl nitrates. We present both laboratory studies that characterise the chemical formation and loss of NO2 in the heated inlets and also result from a first field deployment.
