A graduate of the type used by the Meteorological Service of Canada to gather snowfall amount data across Canada. It was used apparently with a Nipher snow gauge, a meteorological instrument designed by and made by or for the Meteorological Service of Canada.. In Canada, both snow depth and snow/water equivalent are measured and the standard instrument for measuring the latter is the Nipher shielded snow gauge. Since 1953 the MSC has used the Canadian designed Nipher manual gauge at selected stations (Refs.1,2,5). 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). - Function
-
A graduated vessel used to measure melted snow from a snow gauge in order to calculate the amount of snow fallen. - Technical
-
A Meteorological Service of Canada graduate for the 5" Nipher snow gauge (2004.0312) with imperial graduations (Ref. 4). It is graduated for .01 to 50 hundredths of an inch of precipitation in the form of melted snow (Refs. 1-2). This item was probably made before 1971 because it is marked 'M.S.C.' In 1971 the Canadian Meteorological Service of the Department of Transport became the Atmospheric Environment Service (AES) of the Department of the Environment (Ref. 5); the name was changed back to MSC by 1999. Equipment made by or for the Meteorological Service of Canada before 1971 or the Atmospheric Environment Service after 1971 are marked MSC or AES respectively. - Area Notes
