Data Management for Global Change Research Policy
- The U.S. Global Change Research Program requires an early and
continuing commitment to the establishment, maintenance,
validation, description, accessibility, and distribution of high-quality,
long-term data sets.
- Full and open sharing of the full suite of global data sets for all global
change researchers is a fundamental objective.
- Preservation of all data needed for long-term global change research
is required. For each and every global change data parameter, there
should be at least one explicitly designated archive. Procedures and
criteria for setting priorities for data acquisition, retention, and
purging should be developed by participating agencies, both
nationally and internationally. A clearing-house process should be
established to prevent the purging and loss of important data sets.
- Data archives must include easily accessible information about the
data holdings, including quality assessments, supporting ancillary
information, and guidance and aids for locating and obtaining the
- National and international standards should be used to the greatest
extent possible for media and for processing and communication of
global data sets.
- Data should be provided at the lowest possible cost to global change
researchers in the interest of full and open access to data. This cost
should, as a first principle, be no more than the marginal cost of
filling a specific user request. Agencies should act to streamline
administrative arrangements for exchanging data among researchers.
- For those programs in which selected principal investigators have
initial periods of exclusive data use, data should be made openly
available as soon as they become widely useful. In each case, the
funding agency should explicitly define the duration of any
