Application and validation of synergetic cloud property retrieval during the Tropical Warm Pool - International Cloud Experiment (TWP-ICE)

热带暖池-国际云实验（TWP-ICE）将是第一个试图描述热带对流演变的热带实地方案，包括大规模热量、水分和动量收支，同时获得云的详细观测结果（http：//www.bom.gov.au/bmrc/wefor/research/twpice.htm）。热带云的出现对大气能量平衡有重要的影响。我们在慕尼黑大学开发的方法将首次应用于热带条件，通过测量大气边界层的结构，包括边界层云，可以深入了解这些过程。最先进的微波剖面仪-湿度和温度剖面仪（HATPRO）-将是进行详细边界层测量的关键要素。在这方面，将在TWP-ICE主要站点达尔文部署的其他仪器（测云雷达、激光雷达、红外辐射计、辐射测量和降水探测器）特别适合与HATPRO结合使用。与此同时，TWP-ICE计划对热力学大气结构和云微观物理进行的大量原位测量将提供一个独特的机会，在国际背景下验证我们新开发的方法。

The Tropical Warm Pool - International Cloud Experiment (TWP-ICE) will be the first Field program in the tropics that attempts to describe the evolution of tropical convection, including the large scale heat, moisture and momentum budgets, while at the same time obtaining detailed observations of clouds (http://www.bom.gov.au/bmrc/wefor/research/twpice.htm). The occurrence of tropical clouds in the form of shallow non-precipitating cumulus to deep precipitating cumulonimbus with extensive anvils has a significant and fundamental impact an the atmospheric energy balance. The methods we have developed at the University of Munich, which for the first time will be applied to tropical conditions, make it possible to gain insight into these processes by measuring the structure of the atmospheric boundary layer, including boundary layer clouds. A state-of-the-art microwave profiler - the Humidity and Temperature Profiler (HATPRO) - will be a key element for performing detailed boundary layer measurements. In this respect the other instruments to be deployed at the TWP-ICE main site Darwin (cloud radar, lidar, infrared radiometer, radiation measurements and precipitation detectors) are especially suited for combination with HATPRO. At the same time numerous in-situ measurements of the thermodynamic atmospheric structure and of cloud microphysics planned in TWP-ICE will provide a unique opportunity to validate our newly developed methods in an international context.
