The Brewer spectrophotometer has been in operation at some sites almost continuously for up to 25 years. It has also been proven reliable in numerous specialized field campaigns and intercomparisons. In general, the instruments have proven to be quite stable over long periods of time and function reliably in unattended operation for periods of several days under a wide range of operating conditions.

The Brewer spectrophotometer is a valuable scientific tool that has made significant contributions to our understanding of the ozone layer and the dependence of surface UV radiation on stratospheric ozone and other atmospheric variables. Several dozen papers have been published that focus on the instrument itself, and several hundred papers have been published reporting scientific results that include data from Brewer spectrophotometers.
