Reliable long term monitoring of cloud liquid water content under all-weather conditions and the partitioning of total liquid water content into cloud and rain water is mandatory to evaluate the performance of cloud resolving atmospheric models including the newest generation weather forecast models performing in the meso- -scale, and to validate cloud water estimates based on satellite imagery techniques. To this purpose we propose to design, construct, operate, and exploit the data of 1 a novel dual-polarisation three-channel passive ground-based microwave (MW hereafter1) radiometer setup. Run in synergy with several other ground-based remote sensing instruments at Bonn [22 channel passive microwave radiometer (PMWR) MICCY, X-Band precipitation radar, Micro Rain Radar, Ceilometer], Cabauw (3 and 37 GHz cloud radar), and during the field campaign COPS of the DFG-SPP1167 (including among others cloud radars and scanning water vapour lidar), the radiometer will in addition provide unprecedented quantitative information about vertical profiles of cloud microphysical parameters even in raining clouds. Carefully chosen setups will allow for the first time a quantitative evaluation of 3D-effects in radiative transfer in the field.

在全天候条件下对云液态水含量进行可靠的长期监测，并将总液态水含量划分为云和雨水，这对于评估云分辨大气模型的性能，包括最新一代中尺度天气预报模型的性能，以及验证基于卫星图像技术的云水估计是必不可少的。为此，我们建议设计，建造，操作，并利用1一种新的双极化三通道被动地基微波（MW此后1）辐射计设置的数据。与波恩的其他几个地面遥感仪器协同运行[22通道被动微波辐射计MICCY、X波段降水雷达、微降雨雷达、云高计]，Cabauw（3和37 GHz云雷达），并在DFG-SPP 1167的实地活动COPS期间（包括云层雷达和扫描水汽激光雷达等），此外，辐射计还将提供前所未有的有关云微物理参数垂直分布的定量信息，即使是在下雨的云中。精心选择的设置将允许第一次在现场的辐射传输的3D效果的定量评估。
