NASA’s Earth Surface and Interior focus area supports research and analysis of solid-Earth processes and properties from crust to core. This includes providing the space geodetic observations and products foundational to many space missions.
NASA's Climate Briefings series is designed to assist the NASA Headquarters community learn about climate and global change issues.
The series is a service of the Science Mission Directorate's (SMD's) Earth Science Division, a significant contributor to national and worldwide technology, measurements, and research in climate and global change to support scientific understanding and inform policy options.
To ensure uniform and complete implementation of the principles embodied in the NASA Earth science data policy, the following programmatic data system requirements have been created to be utilized in all satellite mission Level 1 Requirements.
*** Note that these requirements are current as of 9 Sep 2011. ***
4.5 MISSION DATA REQUIREMENTS
4.5.1 SCIENCE DATA MANAGEMENT
Products intended to enable users to gain familiarity with the parameters and the data formats.
Product was defined to facilitate data exploration and process studies that do not require rigorous validation. These data are partially validated and improvements are continuing; quality may not be optimal since validation and quality assurance are ongoing.
EOSDIS data products are processed at various levels ranging from Level 0 to Level 4. Level 0 products are raw data at full instrument resolution. At higher levels, the data are converted into more useful parameters and formats. All EOS instruments must have Level 1 products. Most have products at Levels 2 and 3, and many have products at Level 4.
