GEM: GGCM Assembly Project Leader

9300856 Siscoe这是一份NSF GEM项目的提案。GEM项目的最终目标是创建一个地球空间环流模型（GGCM）。GGCM是一种模拟地球磁层行为的模式，就像一般环流模式（GCMs）模拟地球大气层的行为一样。由于gcm是研究全球大气天气和气候的最先进和最强大的计算机代码，因此GGCM将是研究全球磁层过程（也可以称为天气和气候）的最先进和最强大的计算机代码。GEM项目使用一系列多年期、重点突出的活动来提供构建GGCM所需的信息。但是组装本身在项目后期才成为关注的话题。这个建议的要点是现在就开始组织、计划和研究GGCM。在这个时候，总的GGCM组装工作可能相对较小，但是它在引导主要正在进行的运动朝向GEM的最终目标方面的影响可能是巨大的。PI建议承担GEM项目中直接涉及从GEM活动产品中组装GGCM的那部分责任。他建议成立GGCM工作组（GGCM- wg），协调其活动，并管理GEM的GGCM装配项目（GGCM- ap）。因此，他将担任GGCM-AP领导人。因此，他将协调GGCM-WG的活动，安排会议并根据定期日程（以协商一致方式）制定议程。PI将安排负责特定GGCM-WG项目的GGCM-WG子小组的临时会议。项目负责人将通过GGCM-工作组对GGCM的类型和前景进行审查，然后与GGCM-工作组一起制定项目计划，然后在整个项目过程中，将工作组的注意力集中在计划要求的步骤上，从而管理GGCM组装项目。这意味着要牢记整个项目，理解计划中的步骤与项目的关系，并执行这些步骤。在实践中，可以通过选择议程主题、调整会议节奏、在会议之间通过电子邮件工作以及承担一些GGCM-WG任务来执行这些步骤。其中的任务是研究与GGCM装配项目具体相关的问题。作为PI最初的一部分，他建议研究两个具体问题：一个是模块化GGCM中两个基本模块之间的接口问题，另一个是涉及多个模块合作交互的系统集成问题。＊＊＊

9300856 Siscoe This is a proposal to the NSF's GEM program. The GEM program's ultimate goal is to create a Geospace General Circulation Model (GGCM). A GGCM is a model that simulates the behavior of Earth's magnetosphere like general circulation models (GCMs) simulate the behavior of Earth's atmosphere. As GCMs are the most advanced and powerful computer codes designed to study global atmospheric weather and climate, so a GGCM will be the most advanced and powerful computer code to study global magnetospheric processes, which might also be described as weather and climate. The GEM program uses a series of multi-year, foucused campaigns to provide the information needed to assemble a GGCM. But the assembly itself becomes a topic of focus very late in the program. The point of this proposal is to begin the organization, planning, and research leading to a GGCM now. The total GGCM assembly effort at this time can be relatively small, but its effect in terms of guiding the major ongoing campaigns toward GEM's ultimate goal can be great. The PI proposes to assume responsibility for that part of the GEM program that is directly involved with assembling a GGCM out of GEM campaign products. He proposed to organize a GGCM Working Group (GGCM-WG), to coordinate its activities, and to manage GEM's GGCM Assembly Project (GGCM-AP). He will thus function as the GGCM-AP leader. As such, he will coordinate the activities of the GGCM-WG through arranging its meeting and setting its agendas (by consensus) according to a regular calendar. The PI will schedule ad hoc meetings of GGCM-WG subgroups tasked with specific GGCM-WG projects. The PI will manage the GGCM Assembly Project by conducting, through the GGCM-WG, a review of GGCM types and prospects, followed by devising, with the GGCM-WG, a Project Plan, followed by focusing the attention of the WG on the steps called for in the Plan through the course of the Project. This means keeping the total Project in mind, und erstanding how the steps in the Plan relate to the Project, and executing the steps. In practice, one executes the steps by selecting agenda topics, by pacing the meetings, by working through e-mail between meetings, and by taking on some GGCM-WG tasks. Among the tasks are research problems specifically related to the GGCM Assembly Project. As the PI's initial share of these, he proposes to work on two specific problems: one an interface problem between two essential modules in a modularized GGCM, and one a system integration problem involving the cooperative interaction of several modules. ***
