5. NOAA’s Scientific Data Stewardship Program: Implementation, Governance, Performance Measures & Linkages March 29, 2005 5 Data Stewardship is a subset of Data Management and consists of the application of rigorous analyses and oversight to ensure that data sets meet the needs of users (NOSC definition). For environmental satellite observations, SDS priorities include: A.Observing System Performance Monitoring i.Documenting measurement practices and processing practices (metadata) ii.Providing feedback on observing system performance, including recommending corrective action for errant or non-optimal operations. B.Climate Data Records i.Reprocessing (incorporate new data, apply new algorithms, perform bias corrections, integrate/blend data sets from different sources or observing systems) ii.Inter-comparison of data sets for validation Defining Scientific Data Stewardship

Bronze --- Bronze --- A single time series produced by a single analysis team from a single observing system (e.g. MSU) or Silver or Gold level failures to meet Silver --- Silver --- Multiple time series: – produced by multiple analysis teams based a common observing system OR –produced from multiple independent observing systems by a single analysis team (e.g. MSU vs. Radiosondes) Gold --- Gold --- Multiple time series produced by multiple analysis teams from multiple independent observing systems.
