The Randolph Glacier Inventory (RGI 4.0) is a global inventory of glacier
outlines. It is supplemental to the
Global Land Ice Measurements from Space initiative (GLIMS). Production of
the RGI was motivated by the Fifth Assessment Report of the
Intergovernmental Panel on Climate Change (IPCC AR5).
Future updates will be made to the RGI and the GLIMS Glacier Database in
parallel during a transition period. As all these
data are incorporated into the GLIMS Glacier Database and as download tools
are developed to obtain GLIMS data in the RGI data format, the RGI will be
