AB: The Global Emissions Inventory Activity (GEIA) was created in 1990 as an activity of the International Global Atmospheric Chemistry Project (IGAC) - a core project of IGBP. GEIA has been developing and distributing inventories of global gas and aerosol emissions from natural and anthropo-genic sources, The database has sufficient accuracy and spatial and temporal resolution to be currently widely used in global chemistry-transport models, and hence is considered as a standard for Earth sci-ence studies. The inventories provide a scientific foun-dation for assessments dealing with global pollution, global warming, stratospheric ozone depletion, acid precipitation and biological damage. In addition to the inventories, GEIA has summarized the state of the science for each inventory constituent. The list of species, data sets and their documentation, state of science summaries, workshop overviews, planning documents, and a list of the people involved can be obtained from www.geiacenter.org. As a result of the fast development of chemistry-trans-port models and Earth System models, and the large amount of new observational data becoming available, GEIA is entering a new phase. The main objective of GEIA is to "quantify the anthropogenic emissions and natural exchanges of trace gases and aerosols that drive Earth System changes". The poster will detail the different themes within GEIA, as well as the current and future activities, which are either related to integrated or international projects, or driven by scientific or societal issues.
