ACCESS Projects

The objective of NASA's Advancing Collaborative Connections for Earth System Science (ACCESS) Program is to enhance and improve existing components of the distributed and heterogeneous data and information systems infrastructure that support NASA's Earth science research goals.

ACCESS projects increase the interconnectedness and reuse of key information-technology (IT) software and services in use across the broad spectrum of Earth system science investigations.

The ACCESS Program supports the deployment of data and information systems and services that enable the freer movement of data and information within a distributed environment of providers and users, and the exploitation of needed tools and services to aid in measurable improvements of Earth science data access and data usability.

Awarded projects (2015, 2013, 2011, 2009, 2007, 2006, 2005) help to improve NASA's heterogeneous data system components by leveraging proven information technologies, protocols, and practices.

In some cases, the data, information systems, and services are deployed at NASA's Distributed Active Archive Centers (DAACs) or other NASA-related organizations; in these cases the organization is shown in brackets following the title and often has a link for further information.
