Publication of scholarly articles in the Earth, space, and environmental science community is conditional upon the concurrent availability of the data underpinning the research finding, with only a few, standard, widely adopted exceptions, such as around privacy for human subjects or to protect heritage field samples. These data should, to the greatest extent possible, be shared, open, and stored in community-approved FAIR-aligned repositories. Leading repositories provide additional quality checks around domain data and data services and facilitate discovery and reuse of data and other research outputs.
