In 1959 the U.S. Army Corps of Engineers built Camp Century beneath the surface of the northwestern Greenland Ice Sheet. There they studied the feasibility of deploying ballistic missiles within the ice sheet. The base and its wastes were abandoned with minimal decommissioning in 1967, under the assumption they would be preserved for eternity by perpetually accumulating snowfall. Here we show...

Canadian pressure observations and circulation variability: links to air temperature

Slonosky, Victoria C. ; Graham, Edward

In: International Journal of Climatology, 2005, vol. 25(11), p. 1473

A set of 71 station series of surface pressure from Canada and Greenland have been examined for quality control and homogeneity. These records range in length from 50 to 130 years. The object of this exercise was to investigate station-based surface pressure series and atmospheric circulation on a decadal time scale, and to examine the effects of the atmospheric circulation on climate. The data...
