A Canadian made rain gauge accessory of a type used by the Meteorological Service of Canada in gathering precipitation data across Canada. 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 A White & Thomas dip stick for a non-standard 3.6" rain gauge. The MSC copper rain gauge (1987.0598) used an expensive glass graduate (1988.0074 or 1991.0122) which is easily broken. A much less expensive and durable wooden dip stick required that a new gauge be designed. This was tested during WWII and seems to have been used extensively in the prairies. These gauges were distributed by the Saskatchewan Pool in the 1950's. The orifice area was also 100 square inches like the MSC copper gauge. The graduations the dip stick corrected for the water it displaced (Ref. 1).and calibration and instrument maintenance facilities (now largely contracted out). - Function
