Global Inventories of Anthropogenic Emissions of NOx Version 1A from the Global Emissions Inventory Activity (GEIA), IGBP/IGAC

Anthropogenic emissions include emissions from fossil fuel combustion and smelter operations. The annual inventory for NOx emissions (Version 1A) was compiled by Dignon (1992) and was selected to provide the default emissions data for the GEIA NOx inventories. Anthropogenic emissions includes emissions from fossil fuel combustion only.

SO2 and NOx GEIA anthropogenic emissions inventories in the United States and Canada were compiled by the National Acid Precipitation Assessment Program (NAPAP). European anthropogenic emissions of SO2 and NOx were compiled by the Cooperative Program for Monitoring and Evaluation of the Long Range Transmission of Air Pollutants in Europe (EMEP) and by the UN/ECE CORINAIR project. Anthropogenic emissions of SO2 and NOx for Australia were obtained from the Australian Environment Protection Authority (AEPA).

Anthropogenic emissions of SO2 and NOx for South Africa were obtained from the South African Department of National Health and Population Development and the Energy Research Institute of Capetown. Kato and Akimoto (1992) developed inventories of anthropogenic emissions of SO2 and NOx for Asian countries east of Afghanistan and Pakistan. Province and regional estimates are available for China and India.

SO2 inventory emissions for Japan, China, North and South Korea, and Taiwan were developed at the Institute of Behavioral Sciences, Tokyo.
