International Workshop/School on Tracer and Timescale Methods for Understanding Complex Geophysical and Environmental Processes

智力优势：了解自然流体流动中溶解成分的平流扩散输运和产生/破坏过程是地球和环境科学中的一个重要挑战，具有许多不同的应用。此外，地球物理和环境模型通常会产生大量数据。为了理解这些数据，需要新的诊断方法。在这些方法中，越来越流行和强大的方法使用真实的（或假设的）被动示踪剂来标记流体质量和估计传输路径和时间尺度，如示踪剂年龄，停留时间，和过境时间。这些时间尺度导致有见地的诊断，越来越多地应用于跨学科的环境研究。国际讲习班/学校的示踪剂和时间尺度方法理解复杂的地球物理和环境过程将审查和解释已经取得了什么成就，到目前为止，在这一领域，并提出新的发展。这是一次性活动，于2011年8月在比利时举行。鼓励所有对环境示踪理论、建模和观测感兴趣的初级科学家（特别是博士生和博士后）参加。报告将由一个国际示踪技术专家科学委员会的成员发表。此外，学生的口头报告或海报将与模型研究，理论发展，现场测量？用于模型验证或其他目的？或数值模型研究，无论是欧拉还是拉格朗日。诊断可能涉及空气、水、被动/惰性示踪剂、地球化学变量、沉积物颗粒等。更广泛的影响：环境流中示踪剂时标方法的领域将通过研讨会上的学术讨论和随后的合作来推进。讲习班还将有助于教育新一代的年轻研究人员，使他们能够利用示踪时间尺度方法解决广泛的环境问题。

Intellectual Merit: Understanding advective-diffusive transport and production/destruction processes of dissolved constituents in natural fluid flows is an important challenge in Earth and environmental sciences with many diverse applications. Moreover, geophysical and environmental models routinely produce huge amounts of data. To make sense of these data novel diagnostic methods are required. Among these methods an increasingly popular and powerful approach uses real (or hypothetical) passive tracers to tag fluid masses and estimate transport pathways and timescales, such as tracer ages, residence time, and transit time. These timescales lead to insightful diagnoses that are increasingly applied in interdisciplinary environmental studies.The International workshop/school on Tracer and Timescale Methods for Understanding Complex Geophysical and environmental Processes will review and explain what has been achieved so far in this field and suggest new developments. This is one-time event, held in August 2011 in Belgium. All junior scientists (PhD students and post-docs, especially) with interests in environmental tracer theory, modeling and observations are encouraged to participate. Tutorials will be delivered by members of an international scientific committee of experts in tracer techniques. In addition, student oral papers or posters will be presented with model studies, theoretical developments, field measurements ? for model validation or other purposes ? or numerical model studies, be they Eulerian or Lagrangian. The diagnostics may concern air, water, passive/inert tracers, biogeochemical variables, sediment particles, etc.Broader Impacts: The field of tracer timescale methods in environmental flows will be advanced through scholarly discussions at the workshop and collaborations that ensue. The workshop will also contribute to the education of a new generation of young researchers who will be able to use in tracer timescale methods for a broad range of environmental problems.
