RCAF Station Mont Apica
Canadian Forces Station Mont Apica (CFS Mont Apica) was a radar station of the Pinetree Line, located in Mont-Apica, Quebec, Canada, during the Cold War. The station opened as RCAF Station Mont Apica in 1952 and had a staff of some 500 persons at its peak. 2452 AC&W squadron, a reserve unit from Quebec City, trained at Mont Apica until the squadron was disbanded in 1960. Political and technological changes made the station redundant and it closed in 1990. No. 12 Radar Squadron, Mont Apica's lodger unit, was transferred to CFB Bagotville. There was also a weather radar used by the military and later by the Meteorological Service of Canada The Meteorological Service of Canada (MSC; french: Service météorologique du Canada – SMC) is a division of Environment and Climate Change Canada, which primarily provides public meteorological information and weather forecasts and warnings .... After the station's closure, it was transferred to the Lac Castor site of the Canadian weat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Mont Apica
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. The t ...

Pinetree Line
The Pinetree Line was a series of radar stations located across the northern United States and southern Canada at about the 50th parallel north, along with a number of other stations located on the Atlantic Ocean, Atlantic and Pacific coasts. Run by North American Aerospace Defense Command (NORAD) (after its creation), over half were staffed by United States Air Force personnel with the balance operated by the Royal Canadian Air Force. The line was the first coordinated system for early detection of a Soviet Union, Soviet bomber attack on North America, but before the early 1950s radar technology quickly became outdated and the line was in full operation only for a short time. History Plans for what would become the Pinetree Line were underway as early as 1946 within the Permanent Joint Board on Defense (PJBD), a Canadian-U.S. organization. However, the costs of running such a system in the post-war era was too high, and instead Canada concentrated on the areas around Ontari ...

Mont-Apica, Quebec
Mont-Apica is an unorganized territory in the Canadian province of Quebec, located in the regional county municipality of Lac-Saint-Jean-Est. It had a population of 0 in the Canada 2011 Census, and covered a land area of 12.68 km2, entirely within the Laurentides Wildlife Reserve. The territory was home to the former RCAF Station Mont Apica, located along Quebec Route 169 at the base of the namesake Mount Apica. Part of the Pinetree Line and NORAD, the station became operational in 1952 and had a staff of some 500 persons at its peak. Political and technological changes made the station redundant and it closed in 1990. The Apica River, a small tributary of the Pikauba River, flows through the territory in a narrow and deep valley at the foot of the high Mount Apica. The river and mountain were spelled as Upika or Upica until 1961, an Innu word meaning "narrowing river".

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CFB Bagotville
Canadian Forces Base Bagotville , commonly referred to as CFB Bagotville, and also known as Bagotville Airport or Saguenay-Bagotville Airport, is a Canadian Forces base located west of Bagotville in the city of Saguenay.

Weather Radar
Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During World War II, radar operators discovered that weather was causing echoes on their screen, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, surplus radars were used to detect precipitation. Since then, weather radar has evolved on its own and is now used by national weather services, research departments in universities, and in television stations' weather departments. Raw images are routinely used and speciali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorological Service Of Canada
The Meteorological Service of Canada (MSC; french: Service météorologique du Canada – SMC) is a division of Environment and Climate Change Canada, which primarily provides public meteorological information and weather forecasts and warnings of severe weather and other environmental hazards. MSC also monitors and conducts research on the climate, atmospheric science, air quality, water quantities, ice and other environmental issues. MSC operates a network of radio stations throughout Canada transmitting weather and environmental information 24 hours a day called Weatheradio Canada. History Private Observations Prior to 1840, meteorological observations in Canada were made by private individuals, other entities (like HBC), and explorers, but this information was not provided to the general public. Her Majesty's Magnetic and Meteorological Observatory In 1840, British officials ( British Ordnance Department) and the Royal Society established an observatory in Toronto, Canada ...

Canadian Weather Radar Network
The Canadian weather radar network consists of 31 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation, its motion and the threat it poses to life and property. Each had until 2018 a range of in radius around the site to detect reflectivity, 3 angles with a range of , for detecting velocity pattern ( Doppler effect), and an extra long range up to at low elevation angle but strongly folded or aliased (where the maximum unambiguous velocity interval (±Vmax) is less than the full range of velocities being measured which leads to some being displayed with the wrong values). The renewal of the network, from 2018 to 2023, with new S-Band radars brings these numbers respectively to for reflectivity and for full Doppler coverage. Furthermore, the new radars are dual-polarized which means precipitation type can be estimated directly. Starting in June 2021, some of the radars' ranges will be extended to in the lowest ...
