U.S. Global Change Research Program
The Program:
• Coordinates Federal research to
better understand and prepare
the nation for global change
• Prioritizes and supports cutting
edge scientific work in global
change
• Assesses the state of scientific
knowledge and the Nation’s
readiness to respond to global
change
• Communicates research findings
to inform, educate, and engage
the global community

Global Change Research Act (1990), Section 106
…not less frequently than every 4 years, the
Council… shall prepare… an assessment which–
• integrates, evaluates, and interprets the findings
of the Program and discusses the scientific
uncertainties associated with such findings;
• analyzes the effects of global change on the
natural environment, agriculture, energy
production and use, land and water resources,
transportation, human health and welfare,
human social systems, and biological diversity;
and
• analyzes current trends in global change, both
human- induced and natural, and projects major
trends for the subsequent 25 to 100 years.

Global Change Information System
(GCIS)
Long Term Vision:
The Global Change Information System (GCIS) is intended to
eventually become a unified web based source of authoritative,
accessible, usable and timely information about climate and global
change for use by scientists, decision makers, and the public.

Long Term Vision:
The Global Change Information System (GCIS) is intended to

accessible, usable and timely information about climate and global
change for use by scientists, decision makers, and the public.
Initial Prototype:
Coincident with the release of the Third National Climate
Assessment (NCA) on May 6 2014, the GCIS supported the
distribution, presentation and documentation needs of the NCA,
integrating that content into the USGCRP web site and
demonstrating the potential for GCIS to support the long term
vision.

Information Quality Act
•
•
Reproducibility means that the information is capable of being substantially reproduced,
subject to an acceptable degree of imprecision. For information judged to have more
(less) important impacts, the degree of imprecision that is tolerated is reduced
(increased). With respect to analytic results, "capable of being substantially reproduced''
means that independent analysis of the original or supporting data using identical
methods would generate similar analytic results, subject to an acceptable degree of
imprecision or error.
Transparency is not defined in the OMB Guidelines, but the Supplementary Information
to the OMB Guidelines indicates (p. 8456) that "transparency" is at the heart of the
reproducibility standard. The Guidelines state that "The purpose of the reproducibility
standard is to cultivate a consistent agency commitment to transparency about how
analytic results are generated: the specific data used, the various assumptions
employed, the specific analytic methods applied, and the statistical procedures
employed. If sufficient transparency is achieved on each of these matters, then an
analytic result should meet the reproducibility standard." In other words, transparency and ultimately reproducibility - is a matter of showing how you got the results you got.

Data and National Climate Assessment
The Solution
• Defined categories of information within the report:
– Figure
– Image
– Data Source
• Build a process for collecting source information that will satisfy
IQA and HISA requirements:
– Named sources and contacts for every figure, image, and data
source
– Web-based survey that requests inputs that address transparency
and reproducibility and build a foundation for providing the
Metadata ISO 19115 standard
– IT infrastructure that connects and promotes automation between
the web-based survey, a structured data server (SDS)/GCIS, and
publication to an official, interactive NCA web site

GCIS Structured Data Server
• Capture – Obtain from a variety of sources: manual input
by trusted parties – support staff, agency partners, data
centers; automated harvesting from publishers, agency
data centers, etc.
• Identify – Assign persistent, resolvable, controlled
identifiers to each element.
• Organize – Capture, discover and represent relationships
between elements, including across various types of
elements; across data centers; and across agency
boundaries.
• Present – Provide machine accessible interfaces to retrieve
structured metadata, and to search/data mine it.
• Maintain – Develop tools and processes to ensure quality
and integrity of database contents over time.
24
Global Change Content Elements
• Reports, Figures, Images, Research Papers,
Journals, Measurements, Datasets,
Instruments, Agencies, Projects, People,
Models, Algorithms, …
• Findings – “Climate is changing.” “Sea Level
is Rising.”
• Concepts: “Impacts of Climate Change on
Human Health” “Adaptation”

•
•
•
•
RESTful API at data.globalchange.gov
URLs correspond to ontology URIs
Primary storage : RDBMS (PostgreSQL)
Representation is serialized (for JSON) or
used in templates (for Turtle)
• Turtle representation is exported into a
triple store (Virtuoso) which provides a
SPARQL endpoint.
27
GCIS
Ontology
(version
1.2)
(a) Classes and properties representing a brief structure of the NCA3
(b) Classes and properties relevant to the findings of the NCA3 and each
chapter in it
29
(c) Classes and properties about sensors, instruments, platforms, and
algorithms, etc. through which datasets are generated
30
A few classes are asserted as sub-classes of PROV-O classes
Full GCIS Ontology documents are available at:
