The DEW Line was the largest construction project ever undertaken in the Arctic and one of the most difficult construction projects of any kind, ever.
On July 31, 1957, responsibility for the DEW Line passed to the Air Force, and, by the end of that year, the first phase of stations was virtually complete.
The military role of the DEW Line was to detect the approach of Soviet bombers from the north in an actual attack.

  Dew - LoveToKnow 1911   (Site not responding. Last check: 2007-11-06)
Thus the artificial formation of dew and consequent determination of the dew-point is a recognized method of measuring the pressure, and thence the amount of water vapour in the atmosphere.
The amount of dew deposited is considerable, and, in tropical countries, is sometimes sufficiently heavy to be collected by gutters and spouts, but it is not generally regarded as a large percentage of the total rainfall.
The construction of dew ponds is, however, still practised on traditional lines, and it is said that a new dew pond has first to be filled artificially.

 Dry Line: a moisture boundary
Dew points east (ahead) of the dry line shown above range from the upper 50's to low 70's with winds from the southeast.
Air temperatures ahead of the dry line were generally in the 70's and 80's while behind the dry line, temperatures ranged from the mid 80's to mid 90's.
Drier air behind dry lines lifts the moist air ahead of it, triggering the development of thunderstorms along and ahead of the dry line (similar to cold fronts).

 Distant Early Warning Line - Wikipedia, the free encyclopedia
The Distant Early Warning Line, also known as the DEW Line or Early Warning Line, was a system of radar stations in the far northern Arctic region of Canada, with additional stations along the North Coast and Aleutian Islands of Alaska, in addition to the Faroe Islands, Greenland, and Iceland.
The DEW Line was the northernmost and most capable of three radar lines in Canada; the joint Canadian-US Pinetree Line ran from Newfoundland to Vancouver Island, and the Mid-Canada Line ran somewhat north of this.
The majority of Canadian DEW Line stations were the responsibility of the Royal Canadian Air Force (Canadian Armed Forces after 1968) although some manned facilities were jointly staffed with the U.S. Air Force.

 Beaufort Gyre Exploration Project | History | Thule and the DEW Line
In addition to the Thule Air Base, the 1950s saw the establishment of the Distant Early Warning (DEW) line of 63 radar and communication stations.
Extending 3000 miles from Alaska to Baffin Island, roughly along the 69th parallel, the radar stations provided overlapping coverage for the detection of attack by bombers or missiles from the north.
The official DEW line closing ceremony was held in 1993, and the abandoned DEW line facilities are now the focus of a massive cleanup effort by the Canadian government.

 DEW Line Cleanup Project - Environmental Sciences Group - RMC
The DEW Line Cleanup Project, initiated by the Federal Government in 1989, involves the cleanup of 21 radar sites scattered in remote locations, and stretching across 5000 km of the Canadian Arctic.
The DEW Line cleanup strategy was developed during a series of environmental investigations conducted between 1989 and 1994.
Cleanup operations at the DEW Line sites begun in 1996; to date, four of the 21 sites have been cleaned up and work is underway at seven others.

This specifically designed monitor exceeds the requirements set forth by the NFPA and was a collaboration with Airvac Technical Services who are Certified by P.I.P.E. as medical gas inspectors in all 50 US states.
Dew Point is monitored continuously for safety in the DPM-99 in comparison to only 5% of the time as touted by other manufacturers.
Older systems that are "grandfathered" should be upgraded for peace of mind that your MedGas System is not endangering patients with dew points that are higher than the 39ºF mandated by the NFPA.

 DEWLINE HISTORY
The DEW Line - short for Distant Early Warning Line - is an integrated chain of 63 radar and communication systems stretching 3,000 miles from the northwest coast of Alaska to the eastern shore of Baffin Island opposite Greenland.
While few of the original designs for either buildings or equipment were retained, the trial installations did prove that the DEW Line was feasible, and furnished a background of information that led to the final improved designs of all facilities and final plans for manpower, transportation and supply.
The DEW Line extends east and west at roughly the 69th parallel.

 North American Radar
To detect this onslaught, three lines of early warning radar stations were foisted upon the Canadian people: the Pinetree Line, which ran east to west just north of the US border, the Mid-Canada Line, and the arctic Distant Early Warning Line.
The DEW line, many of the stations on which were built in the most inhospitable region on earth, followed the 66th parallel and was completed by 1961.
In reaction to a new generation of Russian bombers, and to the threat of nuclear cruise missiles, the DEW Line was upgraded with fifteen new FPS117 phased-array radars between 1985 and 1994, and re-named the North Warning Line.

 The DEW LINE Sites in Canada, Alaska & Greenland
The DEW Line "Gap Filler" was the AN/FPS-23 continuous wave "fluttar" (Doppler Effect) radar.
The DEW Line's tropospheric scatter lateral (east to west) communication system in Canada and Alaska initially used the AN/FRC-45 produced by Collins Radio Corp. The AN/FRC-45 used "dual diversity" which made it subject to fading as atmospheric conditions changed so it was upgraded by the "Surestop I and Surestop II" programs.
When DEW sites received traffic, the console operator would read the message (which was, 98% of the time, a test message that exercised the equipment) and acknowledged receipt by an entry in the console log.

 Distant Early Warning
A line of old radar stations stretches across the Arctic all the way from northern Alaska to Greenland and Iceland.
On average, the line is about 200 miles / 320 km north of the Arctic Circle and 1,400 miles / 2250 km from the North Pole.
Many of the sites were closed down in the early 1960s, and the importance of the DEW Line decreased after tensions between the United States and Russia lessened.

 Historical Timeline of the Northwest Territories
The DEW Line was a product of the Cold War and was designed to give the American and Canadian military early warning of a Soviet bomber or missile attack ‘over the Pole’.An estimated 25,000 people were involved in the planning and building of the DEW Line.
It took 460,000 tons of material, moved by air, land and water from the United States and Canada to the Arctic, to complete the DEW Line on schedule July 31, 1957.
Though the vast majority of those employed during the construction phase were from the south a report issued in 1958 by Western Electric Corporation, the main construction contractor, praised the few Inuit who were employed.
