Data System Development and Competitive Programs

ACCESS Program

NASA's Advancing Collaborative Connections for Earth System Science (ACCESS) Program develops and implements technologies to effectively manage, discover, and utilize NASA’s archive of Earth observations for scientific research and applications. The program complements NASA’s Earth Observing System Data and Information System (EOSDIS) by engaging external researchers and software developers in NASA's mission to "drive advances in science, technology, aeronautics, space exploration, economic vitality, and stewardship of the Earth" and Strategic Goal 2.2 to "advance knowledge of Earth as a system to meet the challenges of environmental change and to improve life on our planet."

Awarded ACCESS projects (2005, 2006, 2007, 2009, 2011, 2013, 2015, 2017 ) have significantly advanced discovery, management, use, and analysis of large and complex Earth science data sets and have benefited the research and applied science communities.

ACCESS 2013

ACCESS 2013

ACCESS 2013 supports the deployment of data and information capabilities that enable the freer movement of data and information within our distributed environment of providers and users by reusing and modifying existing technologies and information system infrastructure in support of Earth science data and information needs. The use of mature technologies and practices helps lower the overall project risk of system deployment, while making new capabilities readily available to research and applied science communities. The reuse of existing Earth data and information systems infrastructure and interfaces reduces cost, promotes a better environment for technology infusion, and improves NASA’s system of systems infrastructure for our users. Awarded projects are expected to augment NASA’s heterogeneous data system components by leveraging mature information technologies in innovative ways along with existing infrastructure to rapidly deploy capabilities that address specific gaps or weaknesses.

ACCESS 2011

ACCESS 2011

ACCESS 2011 seeks to deploy and reuse existing technological solutions in the support of Earth science data and information needs. The use of mature technologies and practices helps to lower the overall project risk of system deployment, while making these new capabilities readily available to research and applied science communities. Awarded project work plans must focus on the use of higher TRL (technology readiness level) technology components (generally TRL 7 and above). The program encourages targeted solutions to current data access and data usability issues by supplying new tools to our Earth science research community. ACCESS 2011, while focusing on information technology deployment, is centered on addressing the existing needs of research and applied science communities. Proposal teams must include both information technology and Earth science experts, and proposals must be tied directly to Earth science and applied science investigations.

ACCESS 2009

ACCESS 2009

ACCESS 2009 focuses on the following areas of interest.

Improving Earth science user access to web services and service registries

  • Users searching and using NASA Earth science data systems often do not have broad knowledge of services that may be available pertinent to their data of interest. While web-based services have been created that are of direct applicability to Earth science research and applied science uses, many of these services are not easily discoverable or have limited access points. The ACCESS program seeks proposals that address this information gap by providing the means for users to discover and use services being made available by NASA, other Federal agencies, academia, the private sector, and others.

Improving knowledge of NASA’s Earth science data quality and production legacy

  • As data systems become more distributed and users are able to access data from multiple sources, it becomes imperative that users have substantial information about product quality, usability, and legacy of inputs and processes to these data. NASA’s data centers and associated community projects have amassed substantial amounts of information relating to the specific quality and the processing lineage of the data products offered. However, much of this information is available in separate documentation and may not be delivered with the data. NASA is seeking proposals that address this information deficit by helping users better interpret data product metadata, read me files, and other associated materials. Methods for adding value and exposing users to this critical data product information are central to this solicitation. Proposers may also include methods for improving data product knowledge and use by connecting users seamlessly to available product information including science community input on best practices, known errors, and other pertinent information.

ACCESS 2005

The objective of ACCESS 2005 is to further enhance, and in some instances develop, the means for improving the connections of existing conventional pieces of the science data and information infrastructure that support ESSD science communities and their attendant applications and educational users. Proposals selected from the ACCESS 2005 solicitation are expected to rapidly bridge specific gaps in existing information systems and services that support NASA Earth-Sun system science investigations and applications (view NASA's Earth science research strategy at http://science.hq.nasa.gov/earth-sun/science and the applied sciences strategy at http://science.hq.nasa.gov/earth-sun/applications). Proposals that are able to link key needs of the science or application communities with innovative mechanisms for achieving greater data access, use and analysis are of particular value.
