Période

This instrument was apparently in use for 38 years (Ref. 6).

Canada

An example of the type of illuminometer used by the Meteorological Service of Canada from the early 1970's to the 1990's (Refs. 2-5). Few sites in the solar radiation network used the illuminometer. By the early 2000's, the data was no longer being recorded and the instruments were disappearing from the network (Ref. 1). Part of a large collection of meteorological instruments acquired from the Meteorological Service of Canada (previously Atmospheric Environment Service) 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).

Fonction

An instrument designed to measure natural or daylight illumination (RF7), the total visible radiation from the whole dome of the sky.

Technique

An example of an illuminometer, used to measure natural or daylight illumination RF7 (Radiation Field 7), which is the total of visible radiation energy (spectrally weighted between 0,38 and 0.78 micrometres) from the whole dome of the sky. The sensor is a horizontally mounted voltaic cell (Refs. 2-5). The cell is mounted under a metal cover with an opal glass window on the upper surface.
