Dawn Lowe / Andrew Mitchell Status Report on NASA’s Earth Observing Data and Information System (EOSDIS) Dawn Lowe / Andrew Mitchell September 2016

Earth Science Data Systems Mission Statement The Earth Science Data System Program oversees the lifecycle of earth science data with the principle goal of maximizing the scientific return from NASA’s missions and experiments for research and applied scientists, decision makers and society at large.

Topics EOSDIS Overview Metrics Status of NASA SNPP Data Production Future Missions Update on EOSDIS Cloud Technology Prototypes

Data Sources Type Example Missions Satellite/on-orbit Missions Terra, Aqua, Aura, Suomi-NPP, SORCE, GPM, GRACE, CloudSat, CALIPSO, etc. Airborne missions IceBridge, Earth Ventures (5+ missions), UAVSAR, etc. In Situ Measurement missions Field campaigns on land (e.g., LBA-ECO) and in the ocean (e.g., SPURS) Applications support Near-real time creation and distribution of selected products for applications communities Earth Science Research support Research products from efforts like MEaSUREs. This also includes data from older, heritage missions (prior to EOS Program) that the DAACs rescue – e.g., Nimbus, SeaSat

Science Investigator-led Processing Systems National Aeronautics and Space Administration Science Investigator-led Processing Systems Measurements of Pollution in the Troposphere (MOPITT) Ocean Data Processing System (OCDPS) Visible Infrared Imaging Radiometer Suite (VIIRS) Atmosphere MODIS Adaptive Processing System (MODAPS) Ozone Monitoring Instrument (OMI) Visible Infrared Imaging Radiometer Suite (VIIRS) Land Microwave Limb Sounder (MLS) Visible Infrared Imaging Radiometer Suite (VIIRS) Ocean Ozone Mapping Profiler Suite (OMPS) Ozone Advanced Technology Microwave Sounder (ATMS) & Cross-track Infrared Sounder (CrIS) Sounder Tropospheric Emission Spectrometer (TES) Advanced Microwave Scanning Radiometer for EOS 2 (AMSR-E/2) SIPSs perform forward processing of standard products, and reprocess data to incorporate algorithm improvements. www.nasa.gov

Discipline-oriented Data Centers National Aeronautics and Space Administration Discipline-oriented Data Centers ASF SDC SAR Products, Sea Ice, Polar Processes, Geophysics ASF SDC SAR Products, Sea Ice, Polar Processes, Geophysics SEDAC Human Interactions, Land Use, Environmental Sustainability, Geospatial Data LP DAAC Surface Reflectance, Land Cover, Vegetation Indices GES DISC Global Precipitation, Solar Irradiance, Atmospheric Composition and Dynamics, Global Modeling NSIDC DAAC Snow and Ice, Cryosphere, Climate Inter- actions, Sea Ice PO.DAAC Gravity, Sea Surface Temperature, Ocean Winds, Topography, Circulation & Currents CDDIS Space Geodesy, Solid Earth OBPG Ocean Biology, Sea Surface Temperature LaRC ASDC Radiation Budget, Clouds, Aerosols, Tropospheric Chemistry MODAPS/ LAADS MODIS Level-1 and Atmosphere Data Products GHRC DAAC Hydrologic Cycle, Severe Weather Inter- actions, Lightning, Atmospheric Convection ORNL DAAC Biogeochemical Dynamics, Ecological Data, Environmental Processes www.nasa.gov

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

Common Metadata Repository (CMR) EOS Metrics System (EMS) DAAC Context Acquisition, e.g., EOS Data Operations System (EDOS) NASA Sentinel Gateway Science Researchers Processing Science Investigator-led Processing Systems (SIPSs) Raw Data Applications Users Science Data & Data Products Distributed Active Archive Center Mission Processing Systems Educational Users Science Data Science Computing Facilities (SCFs) Ancillary, e.g., EOSDIS Core System / Discipline specific systems Common Metadata Repository (CMR) NOAA NCEP Precipitation Ancillary Data Precise Orbit Determination Metadata Models, e.g., Model Output Global Modeling and Assimilation Metrics EOS Metrics System (EMS) Land Data Assimilation Systems

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.

EOSDIS Cloud Prototypes Web Object Storage and distribution prototype Goals: Store and distribute data from Amazon S3 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.

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.
