This project will apply a new framework of model development for polar science using open source and open platform software with embedded visualization. The group will use the ?Processing? model environment to develop visual models that will allow a better mechanistic understanding of how snow and shrubs independently and interactively affect physical and biological controls over soil N dynamics and decomposition in arctic tundra, and how these in turn affect vegetation composition and productivity. The new visually based applications will, at least to start, use the physics, chemistry and biology that have been incorporated into previous more conventional numerical models. Processing offers a ?friendly? framework for model development that is inherently visually expressive and can be used to rapidly test ideas. It offers accelerated scientific understanding through the visual experience and accelerated model development through the feedback of real time interactivity. It will accelerate the development of mechanistic models by providing a test bed for novel ideas and mechanisms before decisions to incorporate such model components into, for example, the land-surface models of general circulation models. It will enable and encourage observational and experimental scientists to explore models without knowledge of specialized programming languages and thus increase the synergy and collaboration among all parts of the arctic science community. The approach is also ideal for education and outreach as it will allow development of applications that allow students and others to explore scientific concepts easily and intuitively.

该项目将应用一个新的极地科学模型开发框架，使用具有嵌入式可视化的开源和开放平台软件。该组织将使用？处理?模型环境，开发可视化模型，以便更好地理解雪和灌木如何独立和相互作用地影响北极苔原土壤N动态和分解的物理和生物控制，以及这些如何反过来影响植被组成和生产力。新的基于视觉的应用程序，至少在开始的时候，将使用物理、化学和生物学，这些已经被纳入到以前更传统的数值模型中。加工提供了一个友好的？用于模型开发的框架，它具有内在的视觉表现力，并可用于快速测试想法。它通过视觉体验提供加速的科学理解，并通过实时交互的反馈加速模型开发。在决定将这些模型组成部分纳入例如一般环流模型的陆地表面模型之前，它将通过为新想法和机制提供一个试验台来加速机械模型的发展。它将使并鼓励观测和实验科学家在没有专业编程语言知识的情况下探索模型，从而增加北极科学界所有部分之间的协同和协作。这种方法对于教育和推广也是理想的，因为它允许开发应用程序，使学生和其他人能够轻松直观地探索科学概念。
