You can't look anywhere these days without seeing evidence of the changing weather patterns on the earth. Monthly, we are confronted with facts and figures that point to a warming planet.
Climate scientists warn us that inaction could be fatal to our futures here. Military strategists at the Pentagon have [recently cautioned][3] President-Elect Trump that inaction on climate change could spell disaster for our national security as shrinking water supplies and meager rainfall cause crop failures will force large numbers of people to migrate to other parts of the world that can sustain them.
With all of the research on our climate by NASA, the US Defense Department, and others, I was curious if there are open source tools that would allow interested citizens to explore climate data and draw our own conclusions. A quick search of the Internet led me to the [Open Climate Workbench][4], a project that is part of the [Apache Software Foundation][5].
The Open Climate Workbench (OCW) develops software that performs climate model evaluation on data that comes from the [Earth System Grid Federation][6], [Coordinated Regional Climate Downscaling Environment][7], the U.S. Global Change Research Program's [National Climate Assessment][8], the[ North American Regional Climate Assessment Program][9], and from NASA, NOAA, and others.
You can download the OCW's [tar ball][10] and install it on your Linux computer by following the [prerequisites][11]. You can also install the OCW in a virtual machine using Vagrant and a provider like VirtualBox. [Get the instructions][12] for an OCW virtual machine.  
I found the easiest way to see how the OCW works is to download a [virtual machine image][13] from the Regional Climate Model Evaluation System (RCMES).
According to its website, the RCMES "is designed to facilitate regional-scale evaluations of climate and Earth system models by providing standardized access to a vast and comprehensive set of observations (e.g., satellite, reanalyzes and in-situ) and modeling resources (e.g., [CMIP][14] & [CORDEX][15] on the [ESGF][16]), as well as tools for performing common analysis and visualization tasks (e.g., OCW)."
You will need to have VirtualBox and Vagrant installed on your host computer. With it you can see an excellent example of the OCW in operation. The RCMES provides [detailed instructions][17] for downloading, importing, and running the virtual machine. Once your virtual machine is up and running you can log into it with the following credentials.
**Username:vagrant, password:vagrant. **

[Tutorials][18] for the RCMES are available on their website to help you quickly become familiar with the software. The community [is active][19] and they are looking for more [developers][20]. You can [subscribe to their mailing lists][21], too.

使用开源工具探索气候数据的奥秘
============================================================[up][1]

如果这些天地球天气变化的不明显，你几乎无法察觉其中变化的格局。每个月，事实和数据都在向我们诠释一点——全球变暖。
气候学家如是告诫我们——如今的不作为，对于我们的将来可能是致命的。五角大楼高层[最近警告][3]当选总统的川普。申明如果不对气候变化有所动作，可能会造成威胁国家安全的灾难。愈趋减少的的水供应和微薄的降雨量会导致作物歉收，这将迫使大量的移民逃往世界各地，到那些可以维持他们生计的地方去。
遍览 NASA，美国国防部，以及其他机构针对气候的研究成果，我的心中有个疑惑。那就是是否有开源的工具，使对此感兴趣的人们能够自行去探索气候数据的奥秘，并总结出我们自己的结论。我在网上快速的检索了一下，然后找到了[Open Climate Workbench （开源气候工作台）][4]，[Apache 软件基金会][5]旗下的一个工程。
Open Climate Workbench （缩写 OCW） 开发用于对来自[Earth System Grid Federation （地球系统网格联盟，缩写 ESGF）][6]，[Coordinated Regional Climate Downscaling Experiment （协调区域气候降尺度实验，缩写 CORDEX）][7]，美国全球变化研究计划的 [National Climate Assessment （国家气候研究）][8]，[North American Regional Climate Assessment Program （北美区域气候评估计划）][9]，和 NASA，NOAA，以及其他组织或机构的数据进行气候模型评价。
你可下载 OCW 的 [tar ball （压缩包）][10] 并将它安装到满足以下[条件][11]的 Linux 电脑上。也可以将它安装到 Vagrant 或者 VirtualBox 虚拟机中，详见 OCW 的[虚拟机指南][12]。  
个人觉得想要了解 OCW 是如何工作的，最便捷的方式就是到 Regional Climate Model Evaluation System （区域气候模式评价系统，缩写 RCMES）下载一个[虚拟机镜像][13]。
从 RCMES 的网站上看，他们旨在通过为一系列广泛而全面的观测（例如，卫星观测，重新分析，现场观测）和建模资源（例如，[ESGF][16] 上的 [CMIP][14] 和 [CORDEX][15]）提供标准化的访问，以及常规分析和可视化任务的工具（例如，OCW），来促进气候和地球系统模型的区域规模评估。
你需要在宿主机上安装 VirtualBox 和 Vagrant。通过它们，你就能看到一个超赞的 OCW 作业示例。RCMES 为下载，导入，运行虚拟机提供了[详细的说明][17]。当你的虚拟机开始工作时，你可以用以下身份登陆。
** 用户名：vagrant，密码：vagrant。 **

RCMES 网页上的[教程][18]能帮助你迅速上手该软件。他们的[社区][19]十分活跃，而且看上去需要更多的[开发者][20]。 你也可以订阅他们[邮件列表][21]。
工程的[源代码][22]部署在 GitHub 上，遵寻 Apache License, Version 2.0。
