GTN-G Glacier Regions (GlacReg)

Glacier regions are useful for regional assessments of glacier change and other parameters (WGMS 1989, Dyurgerov 2002, Radić and Hock 2010, Pfeffer et al. 2014). This dataset defines 19 first-order glacier regions and more than 90 second-order regions encompassing all of earth’s glaciers and ice caps. It is an update of the RGI dataset 5.0 (Arendt et al., 2015) with some small modifications from the WGMS (2016) glacier regions. Both of these datasets derive ultimately from glacier regions defined by the GLIMS project around the year 2000 and from Radić and Hock (2010). This GTN-G Glacier Regions dataset is a joint set of regions recommended by the Global Terrestrial Network for Glaciers (GTN-G) Advisory Board, the Global Land Ice Measurements from Space initiative (GLIMS), the Randolph Glacier Inventory (RGI) Working Group of the International Association of Cryospheric Sciences (IACS), and the World Glacier Monitoring Service (WGMS). These glacier regions are implemented in RGI 6.0 (RGI Consortium, 2017) and in the Global Glacier Change Bulletin (WGMS 2017).
