What role does convection play in cloud feedbacks within a changing climate? What role does the self-organization of convective clouds play in the climate system? The NARVAL-II campaign will contribute to answers to these key questions in climate science by targeted observations of trade wind convection in the vicinity of Barbados. For this purpose, the German research aircraft HALO will be equipped with a comprehensive suite of cloud remote sensing instruments: a cloud radar detects the vertical cloud structure, a lidar system provides information about the water vapor distribution and aerosols, microwave radiometers allow quantitative estimates of water content in all phases and sensors in the solar frequency range detect cloud geometry and the types of hydrometeors. HALO will be stationed at Barbados in August 2016 for three weeks and will fly research missions for about 95 hours in total. The measurements and derived data products will be provided to the scientific community via the HALO data base. NARVAL-II observations will complement the data record obtained during the NARVAL-I campaign in winter 2013/14 and the measurements during the NAWDEX campaign, which will take place in September 2016 over the high North Atlantic.

在气候变化中对流在云反馈中扮演什么角色？对流云的自组织在气候系统中扮演什么角色？NARVAL-II活动将通过对巴巴多斯附近信风对流的有针对性的观测，为气候科学中这些关键问题的答案做出贡献。为此目的，德国研究飞机HALO将配备一套全面的云遥感仪器：云雷达探测垂直云结构，激光雷达系统提供关于水蒸气分布和悬浮微粒的信息，微波辐射计可对所有阶段的水含量进行定量估计，太阳频率范围内的传感器探测云的几何形状和水凝物的类型。HALO将于2016年8月在巴巴多斯停留三周，并将执行总共约95小时的研究任务。测量结果和由此产生的数据产品将通过哈洛数据库提供给科学界。NARVAL-II观测将补充2013/14年冬季NARVAL-I活动期间获得的数据记录以及NAWDEX活动期间的测量结果，NAWDEX活动将于2016年9月在北大西洋高空进行。
