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 From global EOSDIS perspective to the need for GIBS. Data Metadata as a Service Imagery as a Service Data as a Service Partnerships commercial clouds Today Tomorrow Working Towards
Central Reusable Capabilities Earthdata: the EOSDIS website (http://earthdata.nasa.gov) Metadata Services ECHO: Searchable catalog of granule metadata for NASA datasets (OpenSearch, 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 MapReady Toolkit Sentinel 2 (LPDAAC) (?) Sentinel 3 (ODPS, LAADS, LPDAAC, …) SeaDAS - science processing from Level-1B 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 SeaBASS in situ bio-optical archive, and provide the data as a unified order. In situ SeaBASS archive for product validation and the NOMAD database for bio-optical algorithm development Sentinel 5p Giovanni Subsetting and reformatting SeaDAS - science processing from Level-1B 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. http://seadas.gsfc.nasa.gov/ NRT Image Support - if we did get NRT data, we provide regional data extraction and mapped image delivery services, primarily targeted support active field campaigns. http://oceancolor.gsfc.nasa.gov/sdpscgi/public/subscriptions_home.cgi Match-up to field data - Level-1/Level-2 browser will identify all data granules for which coincident field data exists in the NASA SeaBASS in situ bio-optical archive, and provide the data as a unified order. http://oceancolor.gsfc.nasa.gov/cgi/browse.pl?sen=am Online Validation Tool - online, automated validation analysis for NASA-processed Level-2 products. http://seabass.gsfc.nasa.gov/seabasscgi/search.cgi In general, S3 users will also have access to the in situ SeaBASS archive for product validation and the NOMAD database for bio-optical algorithm development: http://seabass.gsfc.nasa.gov/wiki/article.cgi?article=NOMAD http://seabass.gsfc.nasa.gov/
NASA Sentinel Gateway Leveraging Existing EOSDIS Capabilities For Sentinel 1, 2(?), 3, 5P, 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 L1 products for Sentinel 2, 3 and S5P 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
