Modeling assessments of the atmospheric chemistry, air quality and climatic conditions of the past, present and future require as input inventories of emissions of the appropriate chemical species constructed on appropriate spatial and temporal scales. The task of the Global Emissions Inventories Activity (GEIA) of the International Global Atmospheric Chemistry Project (IGAC) is the production of global inventories suitable for a range of research applications. Current GEIA programs are generally based on addressing emissions by species; these include CO{sub 2}, NH{sub 3}/N{sub 2}O, SO{sub 2}/NO{sub x}, CFC, volatile organic compounds and radioisotopes. In addition a separate program to inventory emissions from biomass burning is also being structured, plus an additional program to address data management issues for all the developing inventories. Program priorities are based on current knowledge and tasks needed to produce the desired inventories. This paper will discuss the different types of global inventories to be developed by the GEIA programs, their key characteristics, and areas to be addressed in the compilation of such inventories. Results of the first GEIA task, a survey of existing inventories and auxiliary data, will be presented. The survey included status assessments for the available inventory information for nineteen different atmospheric species or groups of species on global and regional scales and over time. Of this entire body of information, the only inventory regarded as satisfactory was that for the global emissions of CFCs. An implication of the results of these assessments is that properly gridded emissions inventories are badly needed to support atmospheric modeling calculations on a variety of spatial and temporal scales. Initial studies in the development of global inventories of sulfur dioxide, currently the most advanced GEIA program, will be presented and discussed.
