Recommendation: Data centers and their sponsoring agencies should create independent demonstration data centers aimed at testing applicable technologies and satisfying the data needs of a range of users, including interdisciplinary and nontechnical users. These centers might best prove technological approaches through several participants working in parallel.

Deliberate and appropriate transition to new technology will require planning and testing of technology concepts. In many cases, it is possible to make a gradual transition with periodic migration of datasets and updates to data systems. In other cases, a disruptive transition may be justified. New technologies can help deal with increasing amounts of data, differing data types, changing user communities, and steadily increasing demands of users and data providers. However, in some cases transition will require that software for data ingest, data processing, and data access be rewritten.

Recommendation: Data centers should aggressively adopt newer, more “bleeding edge” technical approaches where there might be significant return on investment. This should be done carefully to minimize the inevitable failures that will occur along the way. Even with the failures, the committee believes the cost savings and improvements for end users will be substantial when compared to the methods practiced today.

The nation’s data centers have achieved notable successes. They store huge volumes of data reliably and provide some widely used and trusted products. The challenges posed by the rapidly expanding quantity and diversity of environmental data and increasing user demands can be met in part through technological solutions. The approaches identified in this report would substantially improve users’ abilities to search for, find, and retrieve information from data centers. The size of the user community would increase, users’ efficacy would improve, and scientific researchers would benefit: all would inevitably improve the information without which policy makers cannot make decisions on climate change.

Although technology can contribute to the solution of important environmental data management problems, human effort is still central to data center operations. Data centers should ensure that the latest technologies are assessed for their relevance and utility. Without question, data centers should not rely solely on technology without continuing to invest in the scientific and human elements of data management and data center operations.
