Satellite Mission Data Systems Requirements
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

a) The <> shall produce the standard science data products listed in Table 1.

b) All data and the standard science data products listed in Table 1, along with the scientific source code for algorithm software, coefficients, and ancillary data used to generate these products will be delivered to the <>, in accordance with the NASA Earth Science Data and Information Policy specified at http://science.nasa.gov/earth-science/earth-science-data/data-information-policy/. Public release of these data shall conform to the NASA Earth Science Data and Information Policy. There shall be no period of exclusive access.

c) Science algorithms used to generate the standard science data products listed in Table 1 shall be documented in Algorithm Theoretical Basis Documents (ATBDs).

d) The <> will coordinate with the <> the release of product versions, to ensure completeness and accuracy of quality information, validation status, and metadata of the <> science data products.

e) The <> will coordinate with the <> on the data and information to be transferred at <> closeout.

4.5.1.1 SCIENCE DATA REQUIREMENTS

a) <> science data product formats shall conform to the <>.

b) The <> science data products metadata shall conform to ISO 19115 Geographic Information – Metadata standards and adhere to the Metadata Requirements – Base Reference for NASA Earth Science Data Products document published at http://earthdata.nasa.gov/about-eosdis/requirements, and the <> shall baseline to a specific initial version before launch.

c) The <> shall transfer to the <> all the information and documentation required for long-term preservation of knowledge about the products resulting from <>, as defined in the NASA Earth Science Data Preservation Content Specification document published at http://earthdata.nasa.gov/about-eosdis/requirements, and shall baseline to a specific initial version.

Additional requirements may be added to this section to provide greater specificity to the science data requirements.
