Update on NASA’s Earth Observing Data and Information System (EOSDIS) Presented to the CEOS WGISS September 29, 2015 Dawn Lowe, ESDIS Project Goddard Space Flight Center

Topics Overview of NASA Data Collections, Platforms, & Instruments New Data Sets and Tools Available from EOSDIS Metrics 2

Data Sources 4 TypeExample 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

New Data Sets Available from EOSDIS: Soil Moisture Active Passive (SMAP) A Global SMAP Soil Moisture Map May 4-11, Beta versions of SMAP Level 1 radiometer & radar data products released to public on July 31: Radiometer data from March 31 to the present is available from the NSIDC DAAC Radar data from April 13 to July 7 is available from the ASF DAAC. (Radar data was halted on July 7 when the radar experienced an anomaly.) SMAP Level 1 Radiometer Imagery now available through GIBS and Worldview.

New Data Sets Available from EOSDIS: Suomi National Polar Orbiting Partnership (SNPP) In the summer of 2014, NASA competitively selected Science Teams and Science Investigator-Led Processing Systems (SIPS) to produce, archive and distribute SNPP products using NASA algorithms, to provide continuity with measurements from the EOS missions: Ozone SIPS: Co-located with OMI SIPS at Goddard VIIRS Land SIPS: Co-located with MODIS at Goddard VIIRS Ocean SIPS: Co-located with Ocean Biology SIPS at Goddard VIIRS Atmosphere SIPS: University of Wisconsin Sounder SIPS: Co-located with AIRS Science Team at JPL NASA’s Distributed Active Archive Centers (DAACs) will distribute SNPP standard data products to the user community.

New Tools: Earthdata Search Client (EDSC) Earthdata Search provides easy-to-use access to EOSDIS services for Earth science data discovery, filtering, visualization, allowing users to: Search for Earth observation data: using the Common Metadata Repository (CMR) for sub-second search across the EOSDIS metadata catalog and simpler, faster access to faceted metadata.Common Metadata Repository (CMR) Preview Earth observation data: Using Global Imagery Browse Services (GIBS), Global Imagery Browse Services (GIBS) Download and access Earth observation data On August 13, 2015, the Earthdata Search Client was released as Open Source software 10

Understanding User Needs and Assessing Performance EOSDIS relies on: DAAC User Working Groups –users representing the DAACs’ science disciplines provide assessments and recommendations based on unique DAAC mission requirements EOSDIS Metrics System – collects metrics on ingest, archive and distribution for evaluation of system performance. Enables ESDIS to characterize and report on use of the EOSDIS DAAC Customer Satisfaction Annual Online survey of all DAAC users to evaluate satisfaction and measure performance Performed by CFI Group, the American Customer Satisfaction Index (ACSI) is the #1 national indicator of customer satisfaction for more than 225 companies and 130 Federal programs in the U.S. 11

13 FY2014 Number of Files Distributed by Discipline

EOSDIS Distribution is World-wide 14 FY2014 EOSDIS Number of Data Products Distributed by Country

EOSDIS American Customer Satisfaction Index (ACSI) EOSDIS sponsors an annual independent customer survey in conjunction with the American Customer Satisfaction Index (ACSI) to: Measure customer satisfaction with NASA Earth Observing System Data and Information System at a national level for each Data Center Identify the key areas that NASA can leverage across the Data Centers to continuously improve its service to its customers Assess the trends in satisfaction with NASA EOSDIS specifically in the following areas: Product Search Product Selection and Order Delivery Product Ease of Use Product Documentation Customer Support Data collection performed via the web

EOSDIS ACSI Customer Satisfaction Survey 2014: Results In 2014 EOSDIS received an ACSI score of 78 (highest ever) Ratings in the mid to upper 70s are considered “very good” by the rating organization, the CFI Group 2014 Survey results are based on 4,147 responses Responses came from 150 different countries Comments in the survey responses help define system improvements, e.g. Bulk delivery of selected data is becoming more and more of an issue as we move to time-series processing of imagery Would like to save searches, otherwise it is o.k. Slightly more than half (53%) of all users were university professors or students

Global Imagery Browse Services and Worldview Driving Goal: To transform how users interact with and discover NASA Earth data; make it visual Approach: – The Global Imagery Browse Services (GIBS) provide open access to full resolution imagery derived from NASA products as web services to mapping clients and scripts – Worldview is an open source, browser- based client to interactively explore GIBS imagery and download the underlying data Open-Access Servers Client

Global Imagery Browse Services and Worldview Underlying data granules can be downloaded from within the application using metadata from CMR
