Advancing Collaborative Connections for Earth System Science (ACCESS)

Advancing Collaborative Connections for Earth System Science (ACCESS) is sponsored by National Aeronautics and Space Administration (NASA). The ACCESS program develops and implements technologies to effectively manage, discover, and utilize NASA's archive of Earth observations for scientific research and applications.

We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

Read about the Web Unification Project The 2019 ACCESS announcement specifically sought technology developments for one or a combination of the following areas: Machine Learning (ML) for Earth Science Data Systems (including new training datasets for ML), Enabling Science in the Cloud, and Improvement, Maintenance, and Support of High-value Open Source Earth Science Tools and Libraries.

Successful proposals clearly identified user communities that will benefit from the technology and demonstrated linkages to pressing Earth science data management problems or the need for open source library and tool maintenance. The Earth Science Division of NASA's Science Mission Directorate selected 11 proposals for three-year awards pending satisfactory budget and work plan negotiations.

The selected investigations are listed below, including Principal Investigator (PI) and institution.
