Poster 21: Global Emissions Inventory Activity — Moving Forward
Paulette Middleton, GEIA Center Director
The Global Emissions Inventory Activity (GEIA) is a major crosscutting activity of the International Global Atmospheric Chemistry (IGAC) Project, a core project of the International Geosphere-Biosphere Program. Since its inception in 1990, GEIA has been providing necessary, quality assured emission inventories for comprehensive global assessments of past, present and future atmospheric chemistry, air quality and climate change. GEIA´s virtual Center at http://geiacenter.org provides data and other timely information on global emissions work. The 2001 GEIA initiatives called for enhanced interaction with the modeling community and expansion of the formal GEIA efforts. As a first step, GEIA now provides short state of science reviews on emissions of individual chemicals and source categories. In early 2003, planning for further expansion of GEIA to better server the global community as a coordinator of crosscutting emissions activities worldwide was initiated. Some of the new topic areas for GEIA´s information distribution activities include: inventories on more flexible levels of spatial and temporal scales; past and future emissions; land-ocean-air exchange activities; emissions modeling; intercomparisons of inventories; and evaluation of emissions/inverse modeling. Possible changes in the meaning of the GEIA acronym to better capture news new activities also are being considered. The summary of the available state of science short reviews and the status of the future of GEIA planning effort will be presented.
