Short summary

The accurate detection of reactive nitrogen species (NO_y) is key to understanding tropospheric ozone production. Typically, NO_y is detected by thermal conversion to NO₂, followed by NO₂ detection. Here, we assess the conversion efficiency of several NO_y species to NO₂ in a thermal dissociation cavity ring-down spectrometer and discuss how this conversion efficiency is affected by certain experimental conditions, such as oven residence time, and interferences from non-NO_y species.
