资源简介:
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. Projection of future trends for a number of key variables are provided
through this section of the DDC (http://ipcc-data.org/sim/gcm_clim/SRES_AR4 ).
The SRES scenarios have been constructed to explore future developments in the global
enviromental with special reference to the production of greenhouse gases and aerosol
precursor emission.
A set of four scenario families (A1, A2, B1, B2) have been developed that each of this
storylines describes one possible demographic, polito-economic, societal and
technological future. Model experiments, also using different forcing scenarios,
were calculated at other modeling centres.
The data represent a subset of data sets from the IPCC Model Output Archive at
PCMDI (https://pcmdi.llnl.gov/mips/cmip3/).
_
These datasets are available in netCDF and GRIB format.
The dataset names are composed of
- centre/model acronym (e.g. MPEH5: Max-Planck-Institute/Echam5)
- scenario acronym (e.g. SRB1: SRES B1)
- run number (e.g. 1: run 1)
- format identifier (e.g. N: netCDF, G: GRIB)
- variable acronym [with level value] (e.g. hur850: relative humidity, 850 hPa)
--> example: MPEH5_SRB1_1_G_hur850
世界气象组织(WMO)与联合国环境规划署(UNEP)共同设立了政府间气候变化专门委员会(IPCC),旨在评估与气候变化理解相关的科学、技术和社会经济信息,包括气候变化的可能影响以及适应和迁移的方案。本数据集部分通过该委员会数据集中心(DDC)的该部分(http://ipcc-data.org/sim/gcm_clim/SRES_AR4)提供了若干关键变量的未来趋势预测。SRES情景构建旨在探索全球环境未来发展的可能性,特别关注温室气体和气溶胶前体排放。共开发了四个情景系列(A1、A2、B1、B2),每个系列的故事线描述了一种可能的、涵盖人口、政治经济、社会和技术方面的未来。此外,在不同建模中心还进行了使用不同强迫情景的模型实验。数据代表来自PCMDI(https://pcmdi.llnl.gov/mips/cmip3/)的IPCC模型输出存档的数据集子集。这些数据集以netCDF和GRIB格式提供。数据集名称由以下部分组成:
- 中心/模型缩写(例如:MPEH5:马克斯·普朗克研究所/Echam5)
- 情景缩写(例如:SRB1:SRES B1)
- 运行编号(例如:1:运行1)
- 格式标识符(例如:N:netCDF,G:GRIB)
- 变量缩写[附带层级值](例如:hur850:相对湿度,850 hPa)
---> 示例:MPEH5_SRB1_1_G_hur850
