AGU Reaffirms the Importance of Long Term Preservation and Access of Geophysical Data

American Geophysical Union (AGU)

The American Geophysical Union (AGU) recently revised and reaffirmed a position statement entitled "The Importance of Long-term Preservation and Accessibility of Geophysical Data." The significance of the role of formal metadata is clearly recognized, and endorsed.

Excerpt from the position statement

Documenting trends and long-term changes is essential for understanding many natural phenomena. Because the state of natural systems is never repeated, data losses, or missed data collection opportunities can never be corrected. Consequently, the value of Earth and space science data grows with time, placing a premium on long-term data curation. Because datasets are often later used for purposes other than those for which they were collected, accurate, complete, and, when possible, standardized metadata are as important as the data themselves. These should include the dataset version number to facilitate future reprocessing of both observational and model or simulation data.
