Permafrost is ground that is frozen for at least two consecutive years. The distribution of permafrost has a major impact on ecosystems and human activities in areas where it is found. Availability and presentation of permafrost data and products can be important for scientists, engineers, policy makers, indigenous communities, and the general public. This project will advance the accessibility of permafrost models in order to help researchers and others who are not permafrost modeling experts to employ models to explore and study permafrost. In particular, the project will promote the online use of permafrost models by students, scientists, and stakeholders. The project will create an Integrated Modeling Toolbox (IMT), consisting of four permafrost models representing a range of capability and complexity. The IMT will provide easy online access to students, stakeholders, and scientists who want to use permafrost models, but lack the expertise and resources to develop them. The IMT will include multiple sets of sample inputs representing a variety of conditions and locations to enable immediate use of any of the permafrost models. The project will also develop open source Visualization Tools with a user-friendly front-end interface to plot model outputs and compare model outputs to observations. Lastly, the project will develop two IMT applications to demonstrate its utility: 1) a high-resolution permafrost map of Alaska and 2) a link between a permafrost model and a geomorphology model. The project also engages students and includes several workshops and meetings to reach out to users and to teach them how to use the permafrost models with hands-on training sessions.

永久冻土是指至少连续两年冻结的地面。 多年冻土的分布对其所在地区的生态系统和人类活动具有重大影响。多年冻土数据和产品的可用性和呈现方式对科学家、工程师、政策制定者、土著社区和公众都很重要。该项目将提高永久冻土模型的可访问性，以帮助研究人员和其他非永久冻土建模专家使用模型来探索和研究永久冻土。特别是，该项目将促进学生，科学家和利益相关者在线使用永久冻土模型。该项目将创建一个综合建模系统（IMT），由四个永久冻土模型组成，代表一系列的能力和复杂性。IMT将为想要使用永久冻土模型但缺乏开发这些模型的专业知识和资源的学生、利益相关者和科学家提供方便的在线访问。IMT将包括代表各种条件和位置的多组样本输入，以便能够立即使用任何永久冻土模型。该项目还将开发具有用户友好前端界面的开放源码可视化工具，以绘制模型输出并将模型输出与观测结果进行比较。最后，该项目将开发两个IMT应用程序，以证明其实用性：1）阿拉斯加的高分辨率永久冻土图和2）永久冻土模型和地貌模型之间的联系。该项目还吸引了学生，包括几个研讨会和会议，以接触用户，并教他们如何使用永久冻土模型与实践培训课程。
