Période

This instrument was apparently in use for 49 years (Ref. 5).

Canada

A radiation measuring instrument of a type used by the Meteorological Service of Canada to gather radiation data. 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 used to measure the radiation from the direct beam of the sun; direct beam RF8 (Radiation Field 8) measurements are made at solar radiation research sites.

Technique

An example of a Linke Fuessner type actinometer. This instrument was used to measure the radiation from the direct beam of the sun. Direct beam (RF8) measurements of the sun which have a 5° degree beam width are made at research sites only. Presently a tracking pyrheliometer is used for this measurement (Ref. 1) This Dutch made instrument has a Moll thermopile, mounted in a thick copper shell consisting of a series of concentric rings screwed one upon another. The heavy mass of the body prevents air currents from unduly affecting the sensor and minimizes any temperature rise due to direct solar radiation, maintaining an uniform temperature in the vicinity of the sensor. The thermopile is divided into two equal sections which are connected in opposition, with one sections screened from radiation and acts a compensating device (Refs. 2-3). See the very similar instrument in the 1982 BMO Handbook (Ref. 3), identified as a pyrheliometer
