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 <<project name>> 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 <<designated NASA Earth Science Division-assigned Data Center(s)>>, 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 <<project name>> will coordinate with the <<designated NASA Earth Science Division-assigned Data Center(s)>> the release of product versions, to ensure completeness and accuracy of quality information, validation status, and metadata of the <<project/instrument name(s)>> science data products.

e) The <<project name>> will coordinate with the <<designated NASA Earth Science Division-assigned Data Center(s)>> on the data and information to be transferred at <<project name>> closeout.

4.5.1.1 SCIENCE DATA REQUIREMENTS

a) <<project/instrument name(s)>> science data product formats shall conform to the <<standard selected from the published list of ESD-approved Data System Standards>>.

b) The <<mission/instrument name(s)>> 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 <<project name>> shall baseline to a specific initial version before launch.

c) The <<project name>> shall transfer to the <<designated NASA Earth Science Division-assigned Data Center(s)>> all the information and documentation required for long-term preservation of knowledge about the products resulting from <<project name>>, 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.

The details in above table shall be jointly determined by the project, Program Scientist, and ESD Data Systems Manager. Note – the data delivery schedule shall be established such that there is NO period of exclusive access to the data.


4.5.2 APPLIED SCIENCE DATA REQUIREMENTS

Beginning in Phase C, the <<project name>> shall organize and host a <<instrument/project name>> data product application workshop annually. The workshop will share information on <<instrument/project name>> science data applications and define potential applications that can be supported with existing <<project name>> data requirements. Results will be provided to the <<project name>> science team and at other <<project name>> workshops and meetings.
