The formation of precipitation is a key process in the trade wind region to maintain a scattered shallow cumulus regime by limiting the growth of the boundary layer and of convective clouds. This effect partly determines how shallow clouds will respond to global warming and whether these clouds accelerate und reduce the climate change. The influencing factors controlling whether a shallow cloud starts to precipitate are yet not fully unraveled, in particular due to a lack of comprehensive observations. The measurement campaign EUREC4A (Elucidating the Role of Cloud-Circulation Coupling in Climate) using the research aircraft HALO will overcome this limitation and provide simultaneously observations of cloud macro- and microphysical properties and the condensate load at the sub kilometer scale as well as estimates of the large scale dynamics and underlying energy and moisture fluxes. EUREC4A will take place at January and February 2020 and explore clouds eats of Barbados. The proposers are part of the international team, which initiated this campaign, and will operate the "HALO microwave package" (HAMP) consisting of microwave radiometers and a cloud radar onboard of HALO. As basis to address the science question we will develop of synergistic cloud and rain retrievals and the extension of a segmented cloud database including also the preceding NARVAL campaigns. This data set is used both for satellite evaluation and to evaluate the next generation of atmospheric models with grid spacing between 100m and a few kilometers.

降水的形成是通过限制边界层和对流云的生长来维持贸易风区域的关键过程。这种效果部分决定了浅云将如何应对全球变暖，以及这些云是否加速und和降低气候变化。控制浅云是否开始沉淀的影响因素尚未完全揭示，尤其是由于缺乏全面的观察结果。使用研究飞机光环的测量活动EUREC4A（阐明气候中云循环耦合在气候中的作用）将克服这一限制，并同时观察到云宏观物理和微物理物理和凝结量的con含量和凝结量，并在次数千数尺度上以及估计大型动力学和下层能量和下层的能量和湿润的液体。 EUREC4A将于2020年1月和2月举行，并探索巴巴多斯的云。提议者是国际团队的一部分，该团队发起了这项运动，并将运营“ Halo Microwave软件包”（HAMP）（HAMP），由微波辐射计和Halo的云雷达组成。作为解决科学问题的基础，我们将开发协同云和降雨检索，以及分段云数据库的扩展，包括先前的鼻腔广告系列。该数据集既用于卫星评估，又用于评估下一代大气模型，网格间距在100m至几公里之间。
