IPCC Data Distribution Centre : First Assessment Report data sets

The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO and UNEP to assess scientific, technical and socio-economic information, relevant for the understanding of climate change, its potential impacts and option for adaption and migration.

This project contains data sets from climate simulations with general circulation model. These calculations are using different forcing scenarios based on emmision scenarios for greenhouse gas and aerosols.
_
This information contained in either IS92 emission scenarios (IPCC 1992) or published model studies using data from these scenarios. Six alternative IPCC scenarios (IS92a to f) were published in the 1992 Supplementary Report to the IPCC Assessment.
These scenarios embodied a wide array of assumption affecting how future greenhouse gas emissions might evolve in the absence of climate policies beyond those already adoped. Model experiments, also using different forcing scenarios, were calculated at other modeling centres. Leggett, J., W.J. Pepper and R.J. Swart, 1992: Emission Scenarios for IPCC: An Update.

政府间气候变化专门委员会（IPCC）由世界气象组织（WMO）和联合国环境规划署（UNEP）设立，旨在评估与气候变化理解、其潜在影响以及适应和迁移选项相关的科学、技术和社会经济信息。本项目中包含了使用一般环流模型进行的气候模拟数据集。这些计算采用了基于温室气体和气溶胶排放情景的不同强迫情景。这些信息包含在IS92排放情景（IPCC 1992）或使用这些情景数据发布的模型研究中。1992年IPCC评估补充报告中发布了六种替代IPCC情景（IS92a至f）。这些情景体现了影响未来温室气体排放如何在没有超出已采纳气候政策的情况下演变的广泛假设。在其他建模中心也进行了使用不同强迫情景的模型实验。Leggett, J., W.J.
