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:

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 PerformanceEOSDIS relies on:
DAAC User Working Groups –users representing the DAACs’ science disciplines provide assessments and recommendations based on unique DAAC mission requirementsEOSDIS 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 webSlide16
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 studentsSlide17
Global Imagery Browse Services and Worldviewhttps://earthdata.nasa.gov/gibs
https://earthdata.nasa.gov/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
