Workshop: Climate over Landscapes; Boulder, Colorado; September 19-21, 2007

UCAR/JOSS、Joe Galewsky(新墨西哥大学)和Gerard Roe(华盛顿大学)之间的这项合作提案是向国家科学基金会提出的请求，以资助2007年9月19-21日在科罗拉多大学举办的题为《景观上的气候》的专题研讨会。过去20年来，地球科学研究中的一些最重大进展是通过了解在大气(气候)、地球表面(地貌)和地壳(构造)中运行的过程的耦合而产生的。通过这种整合，社区基本上改写了理解山脉如何来去、景观如何演变并对外部和内部压力做出反应以及气候和陆地表面如何共同演变的范式。新范式的范围跨越了许多时间和空间尺度，从自然灾害(如山体滑坡)一直到地幔对流。在所有已被发现的重要耦合中，很少有像地表和大气过程--地貌和气候之间的耦合那样基本的。最近的进展使我们能够在大气层群落和地球表面群落之间建立认真的联系：(A)主要通过遥感技术以前所未有的详细程度向我们揭示地貌；(B)低温地质年代学和宇宙成因放射性核素的进展使得能够更可靠地确定具体事件和过程的年代；(C)基于物理的地貌输送规律的理论发展；(D)计算方面的进展使得能够在与地貌有关的尺度上对大气过程进行中尺度模拟；(E)对气候和植被的遥感提供了前所未有的空间和时间观测。我们现在能够知道景观是如何形成的，形成的速度有多快，以及景观的真实面貌。拟议的研讨会旨在将这些进步联系起来。如果要充分利用现有的可能性，让大气科学和景观社区参与是至关重要的。景观动力学可以被视为地球系统科学的一个原型案例研究，它确实跨越了从地壳变形到云微物理的各种过程。各个部分显然都已经就位了。挑战在于作为一个社区走到一起，找出如何尽可能有效地将它们结合在一起。让大气科学和景观动力学社区参与一场关于有效的联合研究方向和可能的合作的对话。对于景观动力学社区：更好地了解有关大气过程的知识，并解决如何将这些知识纳入景观动力学研究。对于大气科学界：了解在研究景观动态方面的新的和令人兴奋的研究机会；通过从不同的角度提出新的问题来挑战和扩展对气候的现有理解。为整个社区和国家科学基金会编写一份白皮书，其目的是提供一份最新的报告和研究议程，由较小一部分讲习班参与者撰写。为了使白皮书具有包容性和尽可能的公开性，我们将向社会传阅草稿，征求意见、建议等。研讨会将邀请15至20名研究生参加。他们参与为未来的研究制定路线将对他们具有启发性，并将有助于确保所提出的想法具有长期影响。跨学科合作是地球科学的未来，而理解景观动态是整个领域面临的巨大挑战之一。从历史上看，进步一直受到传统学科界限的阻碍。这次研讨会是建立更多沟通的持久遗产的机会。

This collaborative proposal between UCAR/JOSS, Joe Galewsky (University of New Mexico) and Gerard Roe (University of Washington) is a request to the National Science Foundation to fund a topical workshop entitled Climate over Landscapes at the University of Colorado, September, 19-21, 2007.Some of the most significant advances in geoscience research over the last 20 years have come about through understanding the coupling of processes operating in the atmosphere (climate), on the Earth's surface (geomorphology), and within the Earth's crust (tectonics). Through this integration, the community is essentially rewriting the paradigm for understanding how mountain ranges come and go, how landscapes evolve and respond to both external and internal forcings, and how climate and the land surface co-evolve. The scope of the new paradigm spans many orders of temporal and spatial scale, from natural hazards (e.g., landslides) all the way through to mantle convection.Of all the couplings that are found to be important, few are as fundamental as that between surface and atmospheric processes - between geomorphology and climate. Recent advances put us in a position to forge serious links between the atmospheric communities and the earth-surface community: a) landscapes are being revealed to us at an unprecedented level of detail, largely though remote sensing techniques; b) advances in low-temperature geochronology and cosmogenic radionuclides allow for more confident dating of specific events and rates of processes; c) the theoretical development of physically-based geomorphic transport laws; d) computational advances permit mesoscale modeling of atmospheric processes on scales relevant to landscapes; and e) remote sensing of climate and vegetation affords unprecedented spatial and temporal observations. We are now able to know how the landscape is shaped, how fast it is shaped, and what the landscape really looks like.The proposed workshop is about connecting these advances. Engaging the atmospheric sciences and landscape communities is critical if full advantage is to be taken of the possibilities available. Landscape dynamics can be seen as an archetypal case study of Earth System Science, spanning as it does, processes ranging from the crust deformation to cloud microphysics. The individual pieces are clearly in place. The challenge is in coming together as a community to figure out how to combine them as effectively as possible.Goals:-1. To engage the atmospheric science and landscape dynamics communities in a conversation about effective joint research directions and possible collaborations.2. For the landscape dynamics community: to get better acquainted with what can be known about relevant atmospheric processes, and to address how that knowledge might be incorporated into landscape dynamics research.3. For the atmospheric sciences community: to learn about the novel and exciting research opportunities in studying landscape dynamics; to challenge and extend existing understanding of climate by asking new questions from different perspectives.4. Generate a white paper for both the community at large and for the NSF, the purpose of which is to provide a state-of-the-art report and a research agenda, to be written by a smaller sub-set of the workshop participants. In order that the white paper is inclusive and as open as possible, we will circulate drafts to the community for comments, suggestions, etc.Broader Impacts:-Educational. 15 to 20 graduate students will be invited to the workshop. Their participation in charting a course for research for the future will be illuminating for them and will help ensure that the ideas raised have a long-term influence.Intellectual. Interdisciplinary collaboration is the future of Earth Sciences, and understanding landscape dynamics is one of the great challenges of the whole field. Historically progress has been impeded by traditional disciplinary boundaries. This workshop is an opportunity to establish a lasting legacy of greater communication.
