Global Emissions Inventory Activity

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 long-term goal has been to develop inventories of all trace species that are involved in global atmospheric chemistry. GEIA is a multi-national effort that draws on the expertise of researchers worldwide to assemble a distributed collection of emission inventories. In 2002, GEIA also began providing short reviews of current understanding of emissions for all of the major chemicals and source types. GEIA provides emission inventories and/or reviews for the following species: - Ammonia - Black Carbon and Organic Carbon - Carbon Dioxide - Carbon Monoxide - CFC-11 - CFC-12 - HCFC-22 - MCF (Methylchloroform) - Dimethylsulfide - Heavy Metals - Mercury - Nitrous Oxide - Methane (Natural) - Methane (Anthropogenic) - Organochlorides - Primary Particles - Radionuclides - Reactive Chloine Emissions - Sulfur and Nitrogen Oxides - Volatile Organic Compounds (Natural) - Volatile Organic Compounds (Anthropogenic)

全球排放清单活动（Global Emissions Inventory Activity，GEIA）于1990年成立，旨在开发并分发源自自然源与人为（人类活动引发，anthropogenic）源的大气气体和气溶胶全球排放清单。其长期目标为构建所有参与全球大气化学过程的痕量物种（trace species）的排放清单。GEIA是一项跨国协作项目，依托全球研究者的专业知识，整合形成分布式排放清单集合。2002年起，GEIA还开始针对所有主要化学品及排放源类型，提供当前排放认知的简要综述。GEIA可为以下物种提供排放清单及/或综述：
- 氨（Ammonia）
- 黑碳与有机碳（Black Carbon and Organic Carbon）
- 二氧化碳（Carbon Dioxide）
- 一氧化碳（Carbon Monoxide）
- CFC-11
- CFC-12
- HCFC-22
- MCF（Methylchloroform，甲基氯仿）
- 二甲基硫（Dimethylsulfide）
- 重金属（Heavy Metals）
- 汞（Mercury）
- 一氧化二氮（Nitrous Oxide）
- 甲烷（自然源，Methane (Natural)）
- 甲烷（人为源，Methane (Anthropogenic)）
- 有机氯化物（Organochlorides）
- 一次颗粒物（Primary Particles）
- 放射性核素（Radionuclides）
- 活性氯排放（Reactive Chlorine Emissions，原文原拼写为Chloine）
- 硫氧化物与氮氧化物（Sulfur and Nitrogen Oxides）
- 挥发性有机化合物（自然源，Volatile Organic Compounds (Natural)）
- 挥发性有机化合物（人为源，Volatile Organic Compounds (Anthropogenic)）
