An In-Depth Look at the Brewer Spectrophotometer

The Brewer Spectrophotometer from Kipp & Zonen is a distinct instrument developed to facilitate automated ozone measurement as part of the World Meteorological Organization’s (WMO) Global Atmosphere Watch (GAW) program.

Environment Canada required the Brewer to offer reliable automatic operation while maintaining high accuracy over long periods of time, irrespective of the environment or climate it is operating in, from frozen regions to the tropics.

The Brewer’s more recent versions can also acquire spectral scans of the ultraviolet (UV) region of solar radiation emanating from the sun and sky.

A number of versions of the Brewer have existed over the years, but the MkIII ‘double’ Brewer is the only model still in production. This is due to its advanced UV measurement capabilities for UVA, UVB, UVE (Erythemal) and UVI (Index).

A network of Brewer instruments is in operation across the globe, installed in locales from deserts to the Antarctic. These robust instruments provide valuable data to the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) – a center based in Toronto and operated by Environment Canada.

The Kipp & Zonen Brewer MkIII Spectrophotometer remains the only currently-produced instrument sanctioned by the World Meteorological Organisation (WMO) for the acquisition of Total Ozone Column (TOC) measurements.
