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.

这是一笔探索性研究的小额赠款，用于在美国宇航局赞助的亚利桑那大学“马塔多尔”项目期间进行额外的观测和分析。 马塔多尔计划于5月至7月在亚利桑那州沙漠的一个地点进行，其目的是记录沙尘暴的特征，这些特征是由远程和现场传感器测量的。 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）从地球表面带入大气层，尽管这些环流的物理性质及其对热量和质量的整体垂直传输的贡献还不清楚。 这笔赠款使部署额外的仪器进行通量测量，并提供了由Renno博士，学生和合作者进行数据分析。 研究的结果将是对边界层中涡流的热量和质量输送的定量估计，以及测试沙尘暴理论模型所需的数据。 马塔多尔项目的这一补充足以激励墨西哥和荷兰学术和研究机构的边界层研究人员开展合作。
