The energy balance of snow and partially snow covered areas in western Greenland
Abstract Surface meteorology and flux data are presented from five sites in a transect crossing a 100‐km‐wide coastal region of west Greenland. The sites cover a variety of Arctic types: snow covered, bog and arid. The measurements show a comparatively small variation of the driving variables: solar...
