Representation of cloud and precipitation processes is one of the largest sources of uncertainty in climate and weather predictions. This project aims at exploring the potential of the novel HALO microwave package (HAMP) for airborne cloud and precipitation research by participating in all cloud related missions of the research aircraft HALO. HAMP is a unique combination of a 23 channel microwave radiometer and a cloud radar. To make HAMP a valuable research instrument, we will develop synergistic retrieval algorithms which convert the measured passive and active microwave signals into profiles of temperature, humidity and hydrometeor content with corresponding error estimates. A comprehensive evaluation of HAMP with existing observational systems, like e.g. satellites and ground based remote sensing super-sites will allow an assessment of its added value. In particular, we will analyze whether HAMP can resolve the fine-scale structure of cloud and precipitation fields and can thus relate point observations with area averaged data from satellites and models. Finally, observations from the NARVAL campaign will be used to demonstrate the benefit of HAMP for model development by revising the frequently used model assumption that shallow convective clouds do not precipitate.

云和降水过程的表示是气候和天气预测中最大的不确定性来源之一。该项目旨在通过参加研究飞机HALO的所有与云有关的任务，探索新型HALO微波包（HAMP）用于空中云和降水研究的潜力。HAMP是23通道微波辐射计和云雷达的独特组合。为了使HAMP成为一种有价值的研究工具，我们将开发协同检索算法，将测得的被动和主动微波信号转换为温度，湿度和水凝物含量的剖面图，并提供相应的误差估计。利用现有的观测系统，如卫星和地面遥感超级站点，对HAMP进行全面评价，将有助于评估其附加值。特别是，我们将分析HAMP是否可以解决云和降水场的细尺度结构，从而可以将点观测与来自卫星和模型的面积平均数据联系起来。最后，NARVAL活动的观测结果将用于证明HAMP对模式发展的好处，方法是修改经常使用的模式假设，即浅对流云不会沉淀。
