Advancing Collaborative Connections for Earth System Science (ACCESS) is an ESDS Competitive Program. The ACCESS program develops and implements technologies to effectively manage, discover, and utilize NASA’s archive of Earth observations for scientific research and applications. ACCESS funding opportunities are solicited through NASA's Research Opportunities in Space and Earth Science (ROSES).
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.
- Advancing an Open-Access Repository for Earth Observation Training Data and Machine Learning Models (Seyed Hamed Alemohammad, Open Imagery Network, Inc.)

- Training Data for Streamflow Estimation (Fritz Policelli, NASA's Goddard Space Flight Center)
ACCESS 2017 teams were required to include both information technology and Earth science expertise, and projects were required to be tied directly to specific issues facing Earth science and applied science users interacting with NASA's Earth Observing System Data and Information System (EOSDIS). Technology focus areas include machine learning, advanced search capabilities, and cloud-optimized preprocessing and data transmission.
The projects with Principal Investigator (PI) and institution:
- Community Tools for Analysis of NASA Earth Observation System Data in the Cloud (Anthony Arendt, University of Washington, Seattle)
- Multi-Temporal Anomaly Detection for SAR Earth Observations (Hook Hua, NASA's Jet Propulsion Laboratory)
- Systematic Data Transformation to Enable Web Coverage Services (WCS) and ArcGIS Image Services within ESDIS Cumulus Cloud (Jeff Walter, NASA's Langley Research Center)
- STARE: SpatioTemporal Adaptive-Resolution Encoding to Unify Diverse Earth Science Data for Integrative Analysis (Michael Rilee, Rilee Systems Technologies, LLC)
- Data Access and the ECCO Ocean and Ice State Estimate (Patrick Heimbach, University of Texas, Austin)
