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, 2015.
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.
• Preview Earth observation data: Using
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

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.

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

Global Imagery Browse Services and Worldview
Driving Goal:
https://earthdata.nasa.gov/gibs
https://earthdata.nasa.gov/worldview
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
Open-Access Servers
– Worldview is an open source, browserbased client to interactively explore GIBS
imagery and download the underlying
data
