Abstract : Observations were conducted in the St. Elias Mountains, Yukon Territory, Canada to determine some aspects of the applicability of thermal remote sensing in the alpine/periglacial environment. Techniques of ground truth observations were tested by which a researcher might determine the usefulness of infrared scanning to his study without the financial investment of airborne remote sensing on a trial-and-error basis. Also, an attempt was made to determine the environmental controls upon radiant temperature by monitoring changing patterns of radiant temperature relative to changing meteorologic conditions. Observations of both actual and thermal infrared radiant temperatures were made over various environmental surfaces in the alpine/periglacial environment. These surfaces included various types of ice-cored moraine, glacial ice, and morainic outwash at the terminal margins of a large valley glacier. (Author)
