EOSDIS as a Seamless, Efficient User Driven System Present NASA’s EOSDIS as an interoperable system of systems where users can select, view, interact and download the data they need transparently from all subsystems in support of interdisciplinary Earth Science research. Supplement current data system capabilities with new interoperable technologies to create a foundation for future evolution. • Support technology infusion of tools developed by internal programs and by industry EOSDIS capabilities and feature development is prioritized through DAAC User Working Groups (science experts) and input from community data system programs Data Today Metadata as a Service Imagery as a Service Tomorrow Data as a Service Partnerships commercial clouds Working Towards

Central Reusable Capabilities Earthdata: the EOSDIS website (http: //earthdata. nasa. gov) Metadata Services • ECHO: Searchable catalog of granule metadata for NASA datasets (Open. Search, CSW, OGC interfaces) • Global Change Master Directory (GCMD): Searchable catalog of over 26, 000 NASA and International dataset collections User Tools (e. g. ) • Reverb – search and order tool • Global Imagery Browse Services (GIBS) – full resolution imagery derived from NASA products in a standardized manner to any web-connected client (Open Sourced) • Worldview - highly responsive interface to explore GIBS imagery and download the underlying data • Giovanni – Quick-Start Exploratory Data Analysis Metrics System (EMS): collects and reports on data ingest, production, archive, and distribution across all EOSDIS data centers User Registration System: provides a centralized and mechanism for user registration and account management for all EOSDIS system.

Examples of Relevant DAAC Capabilities Sentinel 1 (ASF DAAC) • ASF DAAC offers a variety of SAR-derived higher level products via easy-to-use Web interfaces • Map. Ready Toolkit Sentinel 2 (LPDAAC) • (? ) Sentinel 3 (ODPS, LAADS, LPDAAC, …) • Sea. DAS - science processing from Level-1 B through Level-3 with a host of NASA standard and alternative ocean product algorithms (including source code). Also data product analysis and visualization based on ESA's BEAM tool. • Match-up to field data - Level-1/Level-2 browser will identify all data granules for which coincident field data exists in the NASA Sea. BASS in situ bio-optical archive, and provide the data as a unified order. • In situ Sea. BASS archive for product validation and the NOMAD database for bio-optical algorithm development Sentinel 5 p • Giovanni • Subsetting and reformatting 6

NASA Sentinel Gateway Leveraging Existing EOSDIS Capabilities For Sentinel 1, 2(? ), 3, 5 P, NASA will leverage proven gateway and redistribution capabilities, currently used for S-NPP • Single network interface relieves bandwidth load on European networks and • Long term archival and end user distribution by DAACs (e. g. Sentinal 1 by ASF DAAC). • Provides metric reports back to the EC/ESA on product distribution and usage • Leverages entire suite of NASA’s EOSDIS capabilities including capturing and reporting metrics on distribution and usage of Sentinel products by U. S. scientists

Copernicus Support Levels Two support levels for mirroring Sentinel (A and B series) data have been investigated based on guidance. • Level 1 Support: Develop gateway and improve networks to support the transfer, ingest, archival and distribution • L? products for Sentinel 1 • L 1 products for Sentinel 2, 3 and S 5 P • Level 2+ Support: NASA processing centers (e. g. SIPS) create higher level products that are ingested, archived and distributed from designated DAACs. • Costs presented are in addition to Level 1 Support. • Assumption: Science Team involvement and funding to develop higher level products would be required, but are not included in MMOPS overguide submission

S – Copernicus Data Hub System

NASA Gateway for Copernicus Missions ESDIS will develop a NASA Sentinel Data Gateway, which will: • Pull data from the Copernicus Data Hub server (Level 0 or Level 1 data) • Ingest the data, perform checksums to ensure data integrity, and create links in outbound directories for access by DAACs, SIPS, and other external users (e. g. , NRL, NOAA) • Alert operator of missing or defective data • Present status via a web interface of ingested and missing data • Store the data temporarily (32 days) • Export information to the EOSDIS Metrics System to support data accountability activities • Enforce user registration using the User Registration System (URS)

Sentinel 1 A/B Instrument: C-band SAR (5. 405 GHz) • Level-0 products are available to data users in Stripmap (SM), Interferometric Wide swath (IW) and Extra Wide swath (EW) • Wave (WV) product only available as L 2 product (not included) Applications: Monitoring sea ice, oil spills, marine winds & waves, land-use change, land deformation among others, and to respond to emergencies such as floods and earthquakes DAAC: Alaska Satellite Facility NASA Internal Use Only 11
