The Automated Brewer Spectrophotometer

  • Conference paper
Atmospheric Ozone

Summary

The Atmospheric Environment Service and Canadian industry have jointly developed a fully automated version of the Brewer instrument which is now commercially available to the international scientific community. The instrument is gradually being introduced in the World Ozone Network and measurements are currently being made at several sites around the world including Canada, Greece, Germany, Sweden and Belgium.

In the automated mode, the instrument is capable of taking direct sun, zenith sky, UVB and Umkehr measurments in unattended operation for several days. The instrument may be programmed to perform some special routines such as wavelength scanning and sky scanning.

The Brewer spectrophotometer is described and the methods of measuring ozone, SO2 and UVB radiation are outlined. The operation of the fully automated instrument is discussed. Results of routine measurements, intercomparative measurements and special experimental programs are presented.
