This award funds the activities of the Global Analysis, Integration, and Modelling Task Force (GAIM) Office of the International Geosphere Biosphere Program (IGBP). The goal of GAIM is to advance the study of the coupled dynamics of the Earth system using data and models. The challenge of the GAIM office, housed at the University of New Hampshire, is to initiate and facilitate activities that will lead to the rapid development and application of a suite of Global Prognostic Biogeochemical Models. A major new focus for the next three years of GAIM activities will be to enhance the scientific community's capability to address the Earth system as a whole using model coupling and integration. The first challenge will be to coordinate the development of Earth-system Models of Intermediate Complexity (EMICs) by research groups throughout the world. These models show great promise for highlighting critical feedbacks and interactions that control the stability and sensitivity of the Earth system to anthropogenic perturbations. Next, models with system-level integration will be developed that integrate full-complexity subsystem models into Comprehensive Earth System models. Such models pose a different set of challenges to researchers in terms of space, time scale, and boundary conditions.

该奖项资助国际地圈生物圈计划 (IGBP) 全球分析、整合和建模工作组 (GAIM) 办公室的活动。 GAIM 的目标是利用数据和模型推进地球系统耦合动力学的研究。位于新罕布什尔大学的 GAIM 办公室面临的挑战是发起和促进一系列活动，从而促进一套全球预测生物地球化学模型的快速开发和应用。未来三年 GAIM 活动的一个主要新重点将是增强科学界利用模型耦合和集成解决整个地球系统问题的能力。第一个挑战是协调世界各地研究小组开发中等复杂性地球系统模型（EMIC）。这些模型在强调控制地球系统对人为扰动的稳定性和敏感性的关键反馈和相互作用方面显示出巨大的前景。接下来，将开发具有系统级集成的模型，将全复杂性子系统模型集成到综合地球系统模型中。这些模型在空间、时间尺度和边界条件方面给研究人员带来了一系列不同的挑战。
