GEIA is working to advance accessibility to emissions data and observations by improving how databases interact with each other and building on evolving interoperability efforts. Interoperability involves two broad activities:

  • Helping machines talk to each other, by developing standard data exchange protocols, defined data properties, and standard metadata.
  • Helping people talk to each other, by building trust so that people start sharing data, agree on standards and the level of standardization, and define a common (metadata) language.


GEIA is implementing the infrastructure and insights demonstrated by the Community Initiative for Emissions Research and Applications, and working closely with the GEO Air Quality Community of Practice and the Federation of Earth Science Information Partners to develop standards, conventions, and metadata for emissions, observational, and model datasets. Data interoperability will ultimately enable GEIA and its partners to develop on-line visualization and evaluation tools and create a virtual workspace for emissions analysis and forecasting applications.
