The historical review of the total ozone column measurements with the Arosa Brewer triad in operation since 1998 is presented. The calibration history of the different instruments and the data quality control performed at Arosa are described. Over the last 15 years, the Brewer triad shows a dispersion of ∼0.4% between the three collocated instruments and a long‐term stability of ±0.5%. These values are a reference metric achievable with well‐maintained Brewer instruments under favorable measurement conditions.
