Période

after 2006

Canada

An example of the family of radiosondes commonly used by the Meteorological Service of Canada at its 31 upper air observing stations starting in 2006. 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).

Fonction

A device lifted by balloon into the upper atmosphere to measure temperature, humidity, and air pressure and transmit the data to earth. Wind speed and direction were determined by means of the Loran radio navigation system.

Technique

The RS92 replaced the RS80, which was heavier but physically larger. The RS92-KL uses Loran navigation for wind computation. The nine weather stations in the extreme north use the SGP version of the RS92, which uses GPS for wind determination. The sensor package that measures pressure in both radiosondes uses a silicon based chip called a Barocap. They have two humidity sensors that are alternately heated to remove moisture. The temperature sensor is small to reject solar radiation loading. The Meteorological Service of Canada uses Vaisala Digicora II ground equipment with the RS92s. This equipment are able to handle Loran, VLF, and GPS radiosondses.
