SGER: A Pilot Field Experiment on Heat and Aerosol Transport by Dry Convection and Dust Devils

这是一笔小额的探索性研究补助金，用于在美国国家航空航天局赞助的亚利桑那大学“斗牛士”项目期间进行额外的观察和分析。斗牛士计划于5月至7月在亚利桑那州沙漠的一个地点举行，目的是记录通过远程和现场传感器测量的沙尘暴的特征。大气边界层中的涡旋环流--沙尘暴就是一个明显的例子--将热量和颗粒物质(气溶胶)从地球表面带到大气中，尽管这些环流的物理机制及其对整个热量和质量垂直输送的贡献尚不清楚。这笔赠款允许部署更多的通量测量仪器，并为Renno博士、学生和合作者提供数据分析。这项研究的结果将是对边界层中涡旋的热量和质量传输的定量估计，以及检验尘暴理论模型所需的数据。斗牛士项目的这一补充充分鼓励墨西哥和荷兰的学术和研究机构的边界层研究人员进行合作。

This is a Small Grant for Exploratory Research to enable additional observations and analysis during the NASA-sponsored "Matador" project of the University of Arizona. Planned for May-July at a site in the Arizona desert, the purpose of Matador is to document the characteristics of dust devils, as measured by remote and in-situ sensors. Vortex circulations in the atmospheric boundary layer, of which dust devils are a visible example, carry heat and particulate matter (aerosols) from the earth's surface into the atmosphere, though the physics of these circulations and the contribution they make to the overall vertical transport of heat and mass are not understood. This grant enables the deployment of additional instruments for flux measurements and provides for data analysis by Dr. Renno, students, and collaborators. Outcomes of the research will be quantitative estimates of the heat and mass transport by vortices in the boundary layer and the data needed to test theoretical models of dust devils. This supplement to the Matador project is a sufficient incentive to entrain the collaboration of boundary-layer researchers from academic and research institutions in Mexico and The Netherlands.
