Short summary

This study describes the implementation and characterization of the chemical modulation reactor (CMR) used in the laser-induced fluorescence instrument of the Forschungszentrum Jülich. The CMR allows for interference-free OH radical measurement in ambient air. During a field campaign in a rural environment, the observed interference was mostly below the detection limit of the instrument and fully explained by the known ozone interference.
