Greenland surface mass-balance observations from the ice-sheet ablation area and local glaciers

These are historical surface mass balance measurement locations
from Greenland Ice Sheet ablation area and surrounding local
glaciers. There are approximately 3000 unique measurements from 46
sites. The earliest measurements are from 1892. Each measurement is
accompanied with position and date information, as well as quality
and source flags. Users can look to the citation URL for additional
data.
