A prototype instrument designed and built at a Canadian university for use by the Atmospheric Environment Service. Now such instruments, mfd. by Sci-Tec of Saskatoon, are used world wide. The Meteorological Service of Canada is the world calibration centre for all ozone observing equipment and all measurements are referred back to the MSC facility in Toronto (Ref. 1). - Function
-
A spectroscopic device used to photometrically measure relative intensities of spectral lines created by atmospheric ozone, used to monitor levels of ozone in the upper atmosphere. - Technical
-
The Dobson spectrophotometer, developed in the1930s, was the standard instrument until the1960s, when advances in optical design and electronics led to the development of the Brewer spectrophotometer by Alan Brewer of the University of Toronto, and David Wardle, C.T. McElroy and J.B. Kerr of the Atmospheric Environment Service. The latter instrument was a significant improvement, allowing virtually simultaneous observations of sun and sky with more lines being targeted and sequenced in few minutes (Ref. 1). - Area Notes
