This award provides continued funding for the researcher's effort to acquire high-resolution radiosonde data for the United States for use in research on atmospheric turbulence, gravity waves, and the tropopause. While most publicly available US radiosonde data is provided at widely spaced standard pressure levels and a few "significant levels", the raw data has traditionally been archived every 6 seconds, implying a vertical resolution of about 30m. The US National Weather Service is now archiving raw data at one second intervals, so recent data is archived at roughly 5m vertical resolution. This project will use the high-resolution data to conduct research in two areas: studies of turbulent layering in the troposphere above the boundary layer and in the lower stratosphere, and the role of gravity wave breaking in establishing the turbulent layers; and studies of the physical processes that form and maintain the extratropical tropopause.The research has broader impacts for the scientific community by providing estimates for the parameters commonly used in parameterization schemes for gravity waves and turbulence in weather and climate models. In addition, the high-resolution data is made available to the scientifc community through the researcher's website, and the researcher will organize a workshop to help other researchers understand and use the data. The project also supports a graduate student and a postdoc, thereby providing for the next generation of scientists in the field.

该奖项为研究人员努力为美国获取高分辨率辐射数据的努力提供了持续的资金，用于研究大气湍流，重力波和对流层面的研究。 虽然大多数公开可用的美国辐射数据以广泛间隔的标准压力水平和一些“重要级别”提供，但传统上每6秒记录了原始数据，这意味着垂直分辨率约为3000万。 美国国家气象局现在以一秒间隔归档原始数据，因此最近的数据以大约5m的垂直分辨率存档。 该项目将使用高分辨率数据在两个领域进行研究：边界层上方和下层平流层的对流层中的湍流分层的研究，以及重力波破裂在建立湍流层中的作用；以及对形成和维持热带对流层面的物理过程的研究。该研究通过为参数化计划中常用的参数估算为重力波和天气和气候模型中的湍流而对科学界产生更广泛的影响。 此外，高分辨率数据可通过研究人员的网站提供给ScientiFC社区，研究人员将组织一个研讨会，以帮助其他研究人员理解和使用数据。 该项目还支持研究生和博士后，从而为该领域的下一代科学家提供了支持。
