7. Role of EOSDIS DAACs
DAACs were selected and established based on the Earth Science discipline expertise and heritage of their host organizations. They provide unique support and expert services to their user communities.
They also provide data and services to the research community for comprehensive, cross-discipline studies needed to understand Earth as an interrelated system.
DAAC Functions
Ingest Level 0 data from EDOS
Ingest higher level products produced by SIPS
Perform processing of higher level products in some cases
Archive assigned data sets
Export metadata to the Common Metadata Repository (CMR)
Provide user interfaces, tools, and services
Distribute data to users (primarily electronically)
Provide metrics data to ESDIS Metrics System (EMS)
DAACs ensure safe stewardship of NASA’s data

9. EOSDIS-wide Elements and Capabilities
EarthData: the EOSDIS website (Earthdata.nasa.gov) provides a focal point for cross-DAAC and EOSDIS content and news sharing, and access to Earth science data and services
Common Metadata Repository (CMR): metadata catalog of NASA's EOS data and related data services (e.g. reformatting, pattern recognition) as well as Collection-level metadata for ~ 25,000 data sets from broad international community. Essential underlying component for data discovery and access.
EarthData Search Client (EDSC): easy-to-use access to EOSDIS services for Earth science data discovery, filtering, visualization, allowing users to download and access Earth observation data
Near Real-Time Capabilities: Provided by “LANCE” (Land Atmosphere Near real-time Capability for EOS) which produces products within < 3 hours of observation. Near real-time capabilities are co-located with the standard science production facilities.
Global Image Browse System / WorldView: GIBS provides access to full resolution imagery derived from NASA products; Worldview Client allows users to explore GIBS imagery in a Google- Maps like manner.
ESDIS Metrics System (EMS): collects and reports on data ingest, production, archive, and distribution across all EOSDIS data centers
Earthdata Log-in (User Registration System): provides a centralized and simplified mechanism for user registration and account management for all EOSDIS system components.

Capture performance and usage metrics to understand cost drivers for storage and egress fees (tall poles).
Work with Amazon on cost models to support petabyte scale archives.
Status:
ASF WOS is storing data and serving to the public using AWS S3.
Migration of Ingest and storage software is underway.
Ingest/Archive Prototype
Goal:
Develop software to utilize capabilities of commercial clouds for the efficient ingest, archive and management for the unique requirements for satellite, airborne and in situ earth science data.
Phase 1 of prototype demonstrated to DAACs in August
Phase 2 (additional data sets) will begin in October.

23. EOSDIS Cloud Prototypes
Hosting Applications in the cloud offers the clearest path to improve efficiency. Over the next 2 years, core applications will be adapted to work within commercial cloud environments.
Metadata Search and Order System
Common Metadata Repository (CMR): Provides sub-second search and discovery services for over 250M spatial objects using openly available APIs. Catalog of data from all DAACs and many international agencies.
Status: Cloud Migration has begun with creation of the database; anticipate completion in ~ 9 months
Visualization System
Global Imagery Browse Services (GIBS): Full resolution imagery from NASA instruments publically provided through open standards based APIs and the Worldview web client.
Status: Re-engineered GIBS workflow to replicate functionality in the Cloud. Demonstrated with VIIRS imagery. Additional data sets being added.
Earthdata Web Infrastructure
Platform for developing and hosting science websites and portals interacting with spatial data, includes requirement management, code development, testing and deployment to operations.
Status: Developers’ Portal section has been deployed to a Cloud, but is still under development.
Earthdata Login
Centralized mechanism for user self-registration and profile management across EOSDIS
Status: Migration to Cloud put on hold while Earthdata login approach is being re-examined.
