Albedo Measurements of an Arctic Ice Cover From High Towers
Radiometers, suspended at a height of 15 m between two towers anchored to the bottom of the ice cover, have been used to measure the average or integrated albedo of the surface. The work was carried out in May 1967 at Tanquary Fiord, Ellesmere Island (lat. 81° 25′ N., long. 76° 50′ W.) during the pe...
