REVERB - Data and Service Access Client Primary web-based client for discovering and ordering crossdiscipline data from all of EOS Clearing House (ECHO) metadata holdings. Allows users, including those without specific knowledge of the data, to search science data holdings, retrieve high-level descriptions of data sets, view browse images, and submit orders via ECHO to appropriate data providers. Users can submit queries using spatial and temporal criteria and examine search results for relevance using built-in tools. https: //earthdata. nasa. gov/reverb
REVERB - Data and Service Access Client Free Text Search GCMD Science Keywords The GCMD and ECHO repositories will eventually merge to form the Common Metadata Repository (CMR), a single, shared metadata repository for EOSDIS collection and granule level metadata.
LANCE – A Component of EOSDIS The Land Atmosphere Near-real time Capability for EOS (LANCE) is a component of EOSDIS that generates and distributes near real-time (NRT) products from the following instruments: • Terra: MODIS • Aqua: MODIS, AIRS • Aura: OMI, MLS • AMSR-E (Aqua) – ended 2011 • AMSR 2 (GCOM-W 1) – future • MISR (Terra) – being added LANCE Objectives: • To leverage science processing expertise to create high quality NRT products • To provide data to applications community with a maximum latency of 3 hours from observation (The standard, science-quality products are typically available with a latency of 20 -48 hours) • To provide data products with high reliability using redundant systems • To provide an umbrella environment with uniform high level requirements to better serve user needs (Consistency, Collaboration, Coordination) 7

ESDIS Data Discovery Capabilities Worldview (https: //earthdata. nasa. gov/labs/worldview) • Supports time-critical application areas such as wildfire management, air quality measurements, and weather forecasting. • Allows users to interactively browse satellite imagery in near real-time, add layers, and also provides a time series for comparison. GIBS (Global Imagery Browse Services) • GIBS are a set of standard services to deliver global, full-resolution browse satellite imagery in a highly responsive manner • Full Resolution mosaicked layers that are chopped into imagery tiles stored at predefined zoom levels Worldview/GIBS currently consists of: • Routine NRT production of: MODIS (C 5), AIRS, MLS, OMI, Ocean Color • AMSR-E historical data in process of being added – Just added 5 Cryospheric Layers in Arctic, Antarctic and Geographic projections from 2002 -2011 » : Sea Ice Brightness Temperatures (89 H GHz, 89 V GHz), Sea Ice Concentration (12 km, 25 km), Snow Depth over Ice (12 km) • GIBS/Worldview upcoming plans consist of adding: • Routine NRT production of GPM from PPS • Standard SMAP products 9 • MODIS Collection 6 (Forward + Reprocessed)
Continuing Browse Enhancements GIBS and Worldview • Data granules, used to create the imagery are also searchable and can be downloaded through the Worldview interface. • Delivery via Standard Services OGC WMTS / TWMS / KML Clients can be built to use and display images in GIBS – World. View is an example 10

File Transfer Protocol Testing Compared file transfer protocol performance across different network environments in ESDIS Network lab and to Alaska • FTP, FTPS, HTTP, SCP, SFTP, HTTPS, bb. FTP, Grid. FTP • Varied file size, packet loss rate, round-trip time to emulate different network environments Test findings: • Multiple stream file transfer protocols perform best sending large files over networks with high packet loss and long roundtrip times (WAN) • bb. FTP, Grid. FTP • Single stream file transfer protocols perform best sending small files over networks with short round-trip times (LAN) • FTP, FTPS, HTTP • Protocols that encrypt the data are consistently the slowest. For best performance, data encryption should be avoided unless it is a requirement. • SCP, SFTP, HTTPS
Future File Transfer Protocol Work Continue working with DAACs and EOSDIS partners choose the best performing protocols for file transfers • Some DAACs have started incorporating multi-stream protocols, bb. FTP and Grid. FTP, for sending large files Test additional protocols, including Aspera and MMC ftp including tests with JAXA

Future Suomi National Polar-orbiting Partnership Plans for NASA SDS • Current architecture – SNPP data is processed by NOAA IDPS – ESDIS manages the Science Data Segment (SDS) of SNPP and was responsible for product evaluation for VIIRS, Cr. IS, ATMS, OMPS Nadir as well as the production and distribution of CERES, and OMPS Limb – Archive and distribution of SNPP is at NOAA CLASS • Future Architecture – NASA will be producing and distributing it’s own products from all SNPP instruments and potentially future JPSS missions including NRT – Science Investigator-led Processing Systems (SIPS) and Science Teams have recently been selected for the following disciplines: Land, Ocean, Atmosphere, Ozone, Sounder 15
Soil Moisture Active Passive • SMAP Soil Moisture Active Profile • ORR Nov 4 -5, 2014 • Launch Dec 15, 2014, or January 29, 2015 • Downlink to Alaska, Mc. Murdo, Svalbard, Wallops (backup) • 15 contacts per day; 135 GB/day • 3 year mission timeline • SMAP data will be processed to L 0 by EDOS • SMAP science processing will take place at JPL and GSFC/GMAO • Ingest, archive and distribution of SMAP data will be at ASF for Radar data (L 1) and NSIDC for Radiometer data (L 1 -L 4) 16
Preservation NASA is not a “permanent archive” agency Must maintain “researchive” for as long as data are used for scientific research and/or transition responsibility to permanent archives • Researchive responsibilities persist well beyond lives of missions • NASA works with USGS and NARA for long-term preservation • NASA has to ensure data and other critical items are preserved and made available to permanent archival agencies NASA has developed Preservation Content Specifications for Earth Science Data Categories of Data to be preserved include: • Preflight/Pre-Operations • Science Data Products • Mission Data Calibration • Science Data Product Software • Science Data Product Algorithm Input • Science Data Product Validation • Science Data Software Tools • 17
