2020 WDS Data Stewardship Award

The award by the World Data System is related to a collaboration of Ethan Welty with the WGMS. Ethan's sound know­ledge in glacio­logy and infor­mation tech­nology and his personal commit­ment allowed the re­lease of a new version of the Glacier Thick­ness Data­base.

GlaThiDa coverage

This marks a major advance in data compilation and documentation and will serve the glaciological community to better address one of its grand challenges, estimating the total volume of all glaciers on Earth. The database structure, including open-source metadata formats and related software tools, is described in the related paper Worldwide version-controlled database of glacier thickness observations.
