The Key LPIA CCSM3 Dust Cycle Simulations: lpia.x.x_hnx

I. Top Level Description

This dataset archives simulations with Community Climate System Model version 3 (CCSM3) of the dust cycle during a variety of hypothetical conditions during the Late Paleozoic Ice Age.

They were run on the bluefire machine operated by the Computational Information Systems Laboratory (CISL) of the National Center for Atmospheric Research (NCAR) in 2011 and 2012.

The simulations lpia.highstand.vegetation_h2 and lpia.glaciation.big_h2 were used in Marshall et al. (2016), the simulation lpia.lowstand.glaciation.huge_h8rf.tar was used in Sur et al. (2015), and all of the simulations were used in Soreghan et al. (2015). Those publications should be consulted about the design and use of these simulations. All of the simulations are hybridized off simulations archived on Mendeley and associated with Heavens et al. (2015).

More complete documentation is included in the top-level README.TXT

一、 顶层说明
本数据集归档了采用社区气候系统模型第3版（Community Climate System Model version 3, CCSM3）开展的、晚古生代冰期多种假想情境下的尘埃循环模拟结果。

该系列模拟于2011至2012年间，在美国国家大气研究中心（National Center for Atmospheric Research, NCAR）计算信息系统实验室（Computational Information Systems Laboratory, CISL）管理的BlueFire超级计算机上完成。

其中，lpia.highstand.vegetation_h2与lpia.glaciation.big_h2两组模拟结果已被用于Marshall等人（2016）的研究；lpia.lowstand.glaciation.huge_h8rf.tar这组模拟结果被用于Sur等人（2015）的研究；所有模拟结果均被应用于Soreghan等人（2015）的研究中。有关本系列模拟的设计与使用方法，请参考上述已发表文献。

本数据集所有模拟结果均衍生自归档于Mendeley平台、与Heavens等人（2015）研究相关的模拟成果。

更完整的说明文档已收录于顶层目录下的README.TXT文件中。
