The US Global Change Research Program (USGCRP) develops and curates the global information exchange system (GCIS)  to establish “data interfaces and interoperable repositories of climate and global change data. , Maintained and expanded over time. ”  The initial focus of GCIS is to support the United States Third National Climate Assessment (NCA3), which is to publish the results of the transparency and ability of the decision-makers to understand the conclusions and use of the underlying data for their own practical purposes.  
Scope of work
The Earth’s capacity to sustain life. The Earth’s capacity to sustain life.
Global change research includes activities to interact and interact with the Earth system ; The unique environment that the Earth provides for life; Changes that are occurring in the Earth system; And the manner in which such systems are influenced by human actions. 
Provenance and semantics
GCIS has produced information models and ontologies to represent the content structure of the NCA3 and its associated sources . Records of objects and relationships within the GCIS are semantic Web , which can be queried using the SPARQL language. GCIS assigns globally unique persistent identifiers to all entities, activities, and agents relevant to. GCIS namespace,  allowing use of those identifiers for the Semantic Web and other linked datasystems. By categorizing, annotating, And linking provenance information, the GCIS becomes capable of answering provenance-tracking questions about global change research.  
The GCIS Ontology  promotes representation and documentation by incorporating the World Wide Web Consortium (W3C) ‘s recommendation on provenance modeling (PROV) into the design.   The ontology uses the namespace prefix GTIS. A conceptual map of the GCIS Ontology version 1.2  is accessible on the Web.
