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

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.

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.

Initial Prototype:

Coincident with the release of the Third National Climate Assessment (NCA), early 2014, the GCIS will support the distribution, presentation and documentation needs of the NCA, integrating that content into the USGCRP web site (globalchange.gov) and demonstrating the potential for GCIS to support the long term vision.

Nca3 web site

NCA3 Web Site

  • NCA3 will be integrated with the new revision of the USGCRP globalchange.gov

  • Design goals:

    • Responsive design compatible with various screen sizes and devices.

    • Leverages social media to allow users and partners to easily share content and visuals.

    • Expose all elements of NCA3 through web searchable and downloadable PDF.

    • Cater to a wide range of users spanning casual public viewers to scientific researchers.

    • Link to supporting information behind graphics and key messages.


Information quality act

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 the national climate assessment the challenge

Data and The National Climate AssessmentThe Challenge

  • More than 250 named authors (>1000 contributing!)

  • Approximately 1300 pages

  • 30 Chapters

  • 6 Appendices

  • Approximately 300 figures

  • More than 600 images

  • Approximately 83 data sources used across as many as 235 instances*


Data and the national climate assessment the solution

Data and The National Climate AssessmentThe 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

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.

Global change keywords gcmd

Global Change Keywords (GCMD)

Sample finding:

GCMD v8.0

Certain types of extreme weather events have become more frequent and intense, including heat waves, floods, and droughtsin some regions. The increased intensity of heat waves has been most prevalent in the western parts of the country, while the intensity of flooding events has been more prevalent over the eastern parts. Droughts in the Southwest and heat waves everywhere are projected to become more intense in the future.

  • PRECIPITATION > PRECIPITATION RATE

  • EXTREME WEATHER > HEAT/COLD WAVE FREQUENCY/INTENSITY

  • NATURAL HAZARDS > HEAT

Gcis database api

GCIS Database/API

  • RESTful API at data.globalchange.gov

  • URLs correspond to ontology URIs

  • Primary storage : RDBMS (PostgreSQL/PostGIS)

  • 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.
