Short summary
The Brewer spectrophotometer has been used for decades as reference instrument to retrieve total ozone column (TOC) and for validation of satellite based measurements. This spectrophotometer has a thermal sensitivity already known, which is usually characterized using two different retrieval procedures. In this work, we report on a comparative study of the temperature coefficients retrieval procedures, obtaining differences less that 0.08 % in TOC when using any of the procedures.
