IPCC IS92 Emissions Scenarios (A, B, C, D, E, F) Dataset Version 1.1

The Intergovernmental Panel on Climate Change (IPCC) IS92 Emissions Scenarios (A, B, C, D, E, F) Dataset Version 1.1 consists of six global and regional greenhouse gases (GHGs) emissions scenarios projected from 1990 through 2100. The six alternative IPCC scenarios (IS92 A to F) were published in the 1992 Supplementary Report to the IPCC Assessment. These scenarios embodied a wide array of assumptions affecting how future greenhouse gas emissions might evolve in the absence of climate policies beyond those already adopted. The data set was originally produced by IPCC in 1992, and the digital version was re-edited in 2005 to resolve the discrepancies among versions of the data over years. The definitive version of this data set is distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).
To provide the projections of anthropogenic emissions of gases that have the potential to affect climate change.

政府间气候变化专门委员会（Intergovernmental Panel on Climate Change，IPCC）IS92排放情景（A、B、C、D、E、F）数据集版本1.1，包含6组1990年至2100年的全球及区域温室气体（Greenhouse Gases, GHGs）排放情景。这六套备选IPCC情景（IS92 A至F）刊载于《IPCC评估报告1992年补充报告》，其依托一系列假设条件，用于模拟在未额外采取已落地气候政策的前提下，未来温室气体排放的演变路径。该数据集最初由IPCC于1992年编制完成，2005年对数字版本进行了重新编辑，以解决多年来不同数据版本间的不一致问题。本数据集的权威版本由哥伦比亚大学国际地球科学信息网络中心（Center for International Earth Science Information Network，CIESIN）发布。
本数据集旨在提供可能影响气候变化的人为源气体排放预测数据。
