Overview - 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.
The Global Emissions InitiAtive (GEIA), a community effort dedicated to emissions information exchange and competence building, was created in 1990 under the International Geosphere-Biosphere Programme (IGBP) and is now an IGAC activity. GEIA maintains an extensive network of emissions experts covering most source types and world regions, builds emissions data access and analysis platforms, and communicates with the emissions community through online resources and in-person meetings. The GEIA web site is the iniative's virtual communications center.
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.Please view this short slide presentation on GEIA's major efforts. This 2021 presentation describes GEIA and highlights several activities.
Working Groups
GEIA's efforts in emissions analysis are advanced by working groups on specific topics, overarching activities, and through collaborations with other initiatives, science teams, and agencies.
Current working groups include: COVID-19, China Emissions, Africa, Latin America/Carribbean Emissions, VOC Emissions, Urban Emission
Additional working groups will be formed as GEIA-facilitated dialogs identify evolving emissions challenges and establish paths for translating these challenges into new emissions databases.
