IPCC-DDC_CCSRNIES_SRES_A1T: 211 YEARS MONTHLY MEANS National Institute for Environmental Studies and Center for Climate System Research Japan

The SRES data sets were published by the IPCC in 2000 and classified
into four different scenario families (A1, A2, B1, B2).
SRES_A1 storyline describes a future world of very rapid economic
growth, global population that peaks in mid-century and declines
thereafter and the rapid introduction of new and more efficient
technologies.
It is distinguished by their technological emphasis:
A1FI: fossil intensiv,
A1T : non-fossil energy sources and
A1B : a balance across all sources.
The model developed by the Center for Climate System Resaerch/
National Institute for Enviromental Studies in Tokyo consists
of the atmospheric component which has vertical resolution of
20 levels and the triangular truncation at wavenumber 21 (T21).
The ocean model has 17 vertical levels and the same resolution.

The changes of anthropogenic emissions of CO2, CH4, N2O and
sulphur dioxide are prescribed according to the above
mentioned scenario.

SRES数据集于2000年由政府间气候变化专门委员会（IPCC）发布，并被划分为四个不同的情景系列（A1、A2、B1、B2）。其中，SRES_A1情景描述了一个未来世界，其经济增速极快，全球人口在世纪中叶达到峰值随后逐渐减少，并迅速引入了新型且效率更高的技术。该系列以技术导向为特色：A1FI代表化石能源密集型，A1T代表非化石能源，而A1B则实现了所有能源来源的平衡。由东京气候系统研究中心/国家环境研究所开发的模型包括具有20个垂直层级的大气组件，其在21波数处的三角截断为T21。海洋模型同样拥有17个垂直层级，并保持了相同的分辨率。人类活动导致的二氧化碳（CO2）、甲烷（CH4）、氧化亚氮（N2O）和二氧化硫的排放变化均按照上述情景进行规定。
