NASA, NOAA, and USGS collections of Earth science data are large, federated, and have active user communities and collections. Our experience raises five categories of issues for long-term archival: *Organization of the data in the collections is not well-described by text-based categorization principles *Metadata organization for these data is not well-described by Dublin Core and needs attention to data access and data use patterns *Long-term archival requires risk management approaches to dealing with the unique threats to knowledge preservation specific to digital information *Long-term archival requires careful attention to archival cost management *Professional data stewards for these collections may require special training. This paper suggests three mechanisms for improving the quality of long-term archival: *Using a maturity model to assess the readiness of data for accession, for preservation, and for future data usefulness *Developing a risk management strategy for systematically dealing with threats of data loss *Developing a life-cycle cost model for continuously evolving the collections and the data centers that house them.
