This collaborative project among three institutions (the University of Miami, the University of Colorado, and the National Oceanographic and Atmospheric Administration Environmental Technology Laboratory) is part of the "Rain in Cumulus over the Ocean" (RICO) experiment, a coordinated study of precipitation development in trade-wind Cumulus clouds that will involve more than 20 institutions and four countries. In this project, the investigators will use the University-National Oceanographic Laboratory System (UNOLS) ship Seward Johnson, equipped with two short wavelength radars and a scanning Doppler lidar as well as instrumentation to measure fluxes from the ocean surface. These sensors will be used to measure the kinematic and microphysical structures of trade-wind Cumuli, the surrounding air motions, and the boundary-layer fluxes of heat, moisture and momentum. A complementary modeling effort will use large eddy simulation, constrained to match observed characteristics of the clouds, to study cloud-scale processes including entrainment and the roles of cloud condensation nuclei in cloud development. The radars will be positioned near other land-based radars and under the region studied by research aircraft so that the measurements can complement and be compared to those from the other observing systems. The primary science objectives include documenting the lifecycles of tropical cumulus clouds, determining how large drops and precipitation are formed, and learning how precipitation alters the marine boundary layer in the vicinity of trade-wind Cumuli. The expected result of this research will be better understanding of how precipitation is formed in trade-wind cumulus clouds and improved ability to represent the effects of such clouds in climate and other large-scale models. The project includes a substantial educational component. Graduate students involved directly in the research project will gain valuable field experience, and research experience will also be provided through special programs for graduate and undergraduate students not in the field. A K-12 component will include development of middle and high school curricula components suitable for use in classrooms, an onboard research experience for a K-12 teacher, career awareness presentations, and visits by scientists to classrooms. Web-based tools will be used to connect scientists on the cruise to classrooms for interactions with students and teachers, and this connection will continue after the cruise through the analysis phase. An objective will be the development of educational modules that allow students, educators and researchers to contribute to and interact with data related to the Earth system.

这个三个机构（迈阿密大学、科罗拉多大学和国家海洋和大气管理局环境技术实验室）之间的合作项目是“海洋积云降雨”（RICO）实验的一部分，该实验是一项针对信风积云降水发展的协调研究，将涉及 20 多个机构和四个国家。在这个项目中，研究人员将使用大学-国家海洋学实验室系统（UNOLS）的苏厄德·约翰逊号船，该船配备了两个短波长雷达和一个扫描多普勒激光雷达以及测量海洋表面通量的仪器。这些传感器将用于测量信风积云的运动学和微物理结构、周围的空气运动以及热、湿气和动量的边界层通量。补充建模工作将使用大涡模拟，仅限于匹配观测到的云特征，以研究云尺度过程，包括夹带和云凝结核在云发展中的作用。这些雷达将放置在其他陆基雷达附近和研究飞机研究的区域下方，以便测量结果可以补充并与其他观测系统的测量结果进行比较。主要科学目标包括记录热带积云的生命周期，确定雨滴和降水的形成量，以及了解降水如何改变信风积云附近的海洋边界层。这项研究的预期结果将是更好地了解信风积云中降水是如何形成的，并提高在气候和其他大型模型中表示此类云的影响的能力。该项目包括大量的教育内容。直接参与研究项目的研究生将获得宝贵的现场经验，并且还将通过特殊项目为不在该领域的研究生和本科生提供研究经验。 K-12 部分将包括开发适合课堂使用的初中和高中课程部分、K-12 教师的在职研究经验、职业意识演示以及科学家对课堂的访问。基于网络的工具将用于将巡航中的科学家连接到教室，以便与学生和教师互动，并且这种连接将在巡航结束后继续通过分析阶段。一个目标是开发教育模块，使学生、教育工作者和研究人员能够为与地球系统相关的数据做出贡献并与之互动。
