Establishing specifications for the review of scientific data can contribute to the quality of data products and services that are disseminated. Data reviews can take many forms. Ideally, specifications for the review of scientific data include the criteria and the procedures to be employed for conducting such reviews. Specifying and documenting the criteria and procedures for reviewing scientific data enables documentation of the review that was completed for a particular dataset, application of the same criteria and procedures for reviewing multiple datasets over time, and identification of opportunities for improving the criteria and procedures employed for reviewing scientific data. The criteria and procedures for reviewing scientific data at the NASA Socioeconomic Data and applications Center, SEDAC, are described along with recent improvements that have contributed to the quality of scientific data disseminated by SEDAC.
