Application of satellite images for monitoring snow-line in the Yukon and Northwest Territories
Each year, more and more of Canada's vast northern territories are being explored in the search for untapped mineral resources. But the area is covered with snow for seven to ten months a year, which hampers most activities connected with mineral exploration. Snow cover also affects changes in...

Each year, more and more of Canada's vast northern territories are being explored in the search for untapped mineral resources. But the area is covered with snow for seven to ten months a year, which hampers most activities connected with mineral exploration. Snow cover also affects changes in albedo and temperature and hydrologic forecasting. The surface hydrology in most areas is only active for two to five months a year. Historically, snow hydrologists have been limited to the use of ground source measurements for estimating the spatial and temporal variability of snow cover. In the Yukon and Northwest Territories hydrometeorological stations are few and tend to be clustered around settlements. Moreover, the ground source data are subject to error and do not necessarily provide a complete picture of current conditions. The synoptic view provided by satellite images presents an economical way to monitor the retreat and advance of the snow-line and of mapping snow cover in remote and sparsely populated areas. The information may eventually be useful for extrapolating conventional ground source data more effectively over the entire Yukon and Northwest Territories. |
