The Atmospheric Forcing Index (AFI) utilizes standardized scores of the first component from a principal components analysis on the Aleutian Low Pressure Index (ALPI), Pacific Interdecadal Oscillation Index, and the northwesterly atmospheric circulation anomalies for the North Pacific (December...

This index measures the relative intensity of the Aleutian Low pressure system of the north Pacific (December through March). It is calculated as the mean area (km²) with sea level pressure <= 100.5 kPa and expressed as an anomaly from the 1950-1997 mean. A positive index value reflects a...

This index is the cumulative summation of negative northwesterly atmospheric circulation frequency anomalies: Z (westerly), M1, (northwesterly), and M2 (southwesterly) for December through March. An increasing trend in Pacific Circulation Index (PCI) reflects increased westerly and southwesterly...

This publication contains thirteen (13) maps of different biogeochemical and soil properties of forest ecosystems of Canada’s managed forest. A scientific article gives additional details on the methodology: Paré, D., Manka, F., Barrette, J., Augustin, F., Beguin, J. 2021. Indicators of site...

Contained within the 5th Edition (1978 to 1995) of the National Atlas of Canada has a large that shows the extent of permafrost and abundance of ground ice; mapping units are based on physiographic regions. Point data on map give permafrost temperature and thickness for specific sites. The...

Contained within the 1st Edition (1906) of the Atlas of Canada is a map that shows the territorial divisions of Canada. The map displays 1,922.735 sq. miles of unsettled North West Territories, covering what is now Northern Ontario. In addition to this is the northern half of Quebec, which...

Contained within the 1st Edition (1906) of the Atlas of Canada is a map that shows the network and destinations of telegraph lines in Quebec and Maritime Provinces. More then one line may have followed the same route, but only one line is indicated on the map, especially in larger cities....
