Short summary

The hydroxyl radical (OH) largely controls tropospheric trace gas removal and the inverse of OH lifetime, OH reactivity, is a useful measure to investigate the oxidation capacity of the atmosphere. This paper presents a novel method to measure OH reactivity using an operational chemical ionization mass spectrometer (CIMS) for OH measurements at the GAW site Hohenpeissenberg, Germany. It includes the analysis of measurement uncertainties and demonstrates its suitability for long-term monitoring.
