A scale used with the type of sunshine recorded used by Canadian Meteorological Service in Canadian Climate Studies; Campbell-Stokes Recorders have been used in Canada since at least the 1920s A piece of meteorological equipment from a large collection of meteorological instruments used by the Meteorological Service of Canada (previously Atmospheric Environment Service) and acquired by the CSTM since 1967. MSC is the government agency responsible for collecting and disseminating meteorological data and forecasts in Canada. It was founded in 1871 in Toronto where it is still headquartered. The MSC was originally on the University of Toronto downtown campus but moved to Downsview in 1971 on land owned by UofT. The headquarters houses laboratories, research facilities and calibration and instrument maintenance facilities (now largely contracted out). - Function
-
An device used to measure burnt paper from a Campbell-Stokes sunshine recorder, an instrument that measure the duration of sunshine. - Technical
-
The Campbell-Stokes recorder is basically a recording sundial, invented in 1853 and adapted to use paper charts in 1879. The recorder's sphere of optical glass collects sunshine, which burns a track in a specially prepared card. The plastic scale is laid on the burnt paper to measure the number of hours for which the sun's rays shone. - Area Notes
