- Аннотация: The Randolph Glacier Inventory (RGI) is a globally complete inventory of glacier outlines. It is supplemental to the database compiled by the Global Land Ice Measurements from Space initiative (GLIMS). While GLIMS is a multi-temporal database with an extensive set of attributes, the RGI is intended to be a snapshot of the world’s glaciers as they werenear the beginning of the 21st century(although in fact its range of dates is still substantial). Production of the RGI was motivated by the preparation of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). The RGI was released initially with little documentati on in view of the IPCC’s tight deadlines during 2012. More documentation is provided in the current version of this Technical Report. The full content of the RGI has now been integrated into the database of GLIMS. However work remains to be done to make the RGI a downloadable subset of GLIMS, offering complete one-time coverage, version control and a standard set of attributes.The RGI was not designed for the measurement of glacier-by- glacier rates of area change, for which the greatest possible accuracy in dating, delineation and georeferencing is essential. Many RGI outlines pass this test, but in general ompleteness of coverage has had higher priority. Rather, the strength of the RGI lies in the capacity it offers for handling many glaciers at once, for example for estimating glacier volumes and rates of elevation change at regional and global scales and for simulating cryospheric responses to climatic forcing.
