About GEIA

Quantification of chemical emissions into the air is a key step in explaining observed variability and trends in atmospheric composition and in attributing these observed changes to their causes on local to global scales. Accurate emissions data are necessary to identify feasible controls that reduce adverse impacts associated with air quality and climate, to track the success of implemented policies, and to estimate future impacts. GEIA is a community effort that builds bridges between environmental science and policy, by bringing together people, data, and tools to create and communicate the highest quality information about emissions. GEIA seeks to enhance access to emissions data, facilitate analysis to improve the scientific basis for emissions information, and strengthen the emissions community.


The GEIA web site is designed to enhance interactivity among the GEIA community, expand access to emissions information, and enrich emissions analysis and understanding.  We invite existing members and new visitors to GEIA to become registered users, let us know about your interests and expertise, provide comments on the web site, and add to the online calendar of events. We intend this site to become the primary communication method for the GEIA network. Over the next few months our registered users will also be able to contribute to the new searchable bibliography; join working groups on key topics in emissions; participate in online forums on emission challenges, analysis tools, and data bases; and upload information for the upcoming GEIA 2014 Conference in Boulder, Colorado, next June.  When you register to become a site user, you will have the opportunity to keep your profile information private or share it with others in the GEIA community.   Our GEIA network and web site management team looks forward to your contributions; by working together, we will achieve GEIA’s 2020 vision for better emissions understanding.
