Global Emissions Inventory Activity (GEIA)
Computer model assessments of past, present, and future atmospheric chemistry rely on inventories of emissions constructed on appropriate spatial and temporal scales with appropriate chemical species. The Global Emissions Inventory Activity (GEIA) was created in 1990 to develop and distribute global emissions inventories of gases and aerosols emitted into the atmosphere from natural and anthropogenic (human-caused) sources. The inventory includes emissions from vegetation fires. The long-term goal is to develop inventories of all trace species that are involved in global atmospheric chemistry. GEIA and the Biomass Burning Experiment (BIBEX) are activities of the International Global Atmospheric Chemistry (IGAC) Project. IGAC is a Core Project of the International Geosphere-Biosphere Programme (IGBP).
