Turbulence in the atmosphere near the earth's surface determines the transport and mixing of airborne substances. Understanding turbulent dispersion near the surface is important in developing new techniques for monitoring greenhouse gas exchange, for predicting the fate of pollutants, for studying the physical processes underlying ecosystem functioning, and for a host of other applications. This research program will pursue novel methods of describing turbulent dispersion. Part of the work will focus on expanding current theoretical descriptions to new scenarios, while the other part will focus on experiments to verify and improve our models of turbulent dispersion.

地球表面附近大气中的湍流决定了气载物质的输送和混合。了解近地表的湍流扩散对于开发监测温室气体交换的新技术、预测污染物的命运、研究生态系统功能的物理过程以及许多其他应用都很重要。 这项研究计划将追求描述湍流扩散的新方法。部分工作将集中在扩展当前的理论描述到新的场景，而另一部分将集中在实验，以验证和改进我们的湍流扩散模型。
