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.
