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.

GEIA Overview

May 2021

GEIA, a major crosscutting activity of IGAC https://igacproject.org, is an international community effort dedicated to emissions understanding, information exchange, and competence building. Since it was created in 1990 under the International Geosphere-Biosphere Programme (IGBP), GEIA has been providing necessary, quality assured emission information for comprehensive global assessments of past, present and future atmospheric chemistry, air quality and climate change. GEIA’s ongoing initiatives advance understanding, distribution and use of timely information to the research, assessment and policy communities.  GEIA also provides information on emissions on regional and megacity scales, assesses land-water-air exchange processes, and develops platforms for information sharing and data evaluation.  The NASA-sponsored GEIA Web Site works with the international GEIA Scientific Steering Committee to coordinate GEIA planning efforts, develop and implement outreach strategies, and make effective distribution of datasets and related information possible. GEIA's major efforts are summarized here.
