抽象。HD（CP）2观察性原型实验（HOPE）于2013年4月和5月在德国Julich进行了为期2个月的主要田间实验，随后于2013年9月在德国Melpitz进行了较小规模的活动。HOPE的目的是提供一个观测数据集，以便在模型模拟规模上对新的德国共同体大气二十面体非流体静力学模型进行严格评价，并进一步提供关于陆面大气边界层交换、云和降水过程以及需参数化的次网格变率和微物理特性的信息。HOPE的重点是对流大气边界层中云和降水的开始。本文总结了仪器设置，密集的观察期，并从两个运动的例子结果。HOPE-Julich仪器包括一个无线电探测站，4个多普勒激光雷达，4个拉曼激光雷达（其中3个提供温度，3个提供水蒸气，所有这些都提供粒子后向散射数据）、1个水蒸气差分吸收激光雷达、3个测云雷达、5个微波辐射计、3个测雨雷达、6个天空成象仪、99个总日射计和5个太阳光度计，其中一些是协同作用。HOPE-Melpitz活动将气溶胶和云的地面遥感与直升机和气球在大气柱和地面的现场观测结合起来。HOPE在一个大约10 × 10 × 10 km 3的立方体内以高的空间和时间分辨率提供了前所未有的气溶胶、云和降水的大气动力学、物理学和微观及宏观物理特性的集合。HOPE数据将大大有助于我们了解边界层动力学和云和降水的形成。这些数据集已通过一个专门的数据门户网站提供。HOPE数据在模式评估中的首次应用表明，观测和模拟的边界层高度、湍流特性和云量之间基本一致，但它们也指出了值得从观测和模拟的角度进一步研究的显著差异。

Abstract. The HD(CP)2 Observational Prototype Experiment (HOPE) was performed as a major 2-month field experiment in Julich, Germany, in April and May 2013, followed by a smaller campaign in Melpitz, Germany, in September 2013. HOPE has been designed to provide an observational dataset for a critical evaluation of the new German community atmospheric icosahedral non-hydrostatic (ICON) model at the scale of the model simulations and further to provide information on land-surface–atmospheric boundary layer exchange, cloud and precipitation processes, as well as sub-grid variability and microphysical properties that are subject to parameterizations. HOPE focuses on the onset of clouds and precipitation in the convective atmospheric boundary layer. This paper summarizes the instrument set-ups, the intensive observation periods, and example results from both campaigns. HOPE-Julich instrumentation included a radio sounding station, 4 Doppler lidars, 4 Raman lidars (3 of them provide temperature, 3 of them water vapour, and all of them particle backscatter data), 1 water vapour differential absorption lidar, 3 cloud radars, 5 microwave radiometers, 3 rain radars, 6 sky imagers, 99 pyranometers, and 5 sun photometers operated at different sites, some of them in synergy. The HOPE-Melpitz campaign combined ground-based remote sensing of aerosols and clouds with helicopter- and balloon-based in situ observations in the atmospheric column and at the surface. HOPE provided an unprecedented collection of atmospheric dynamical, thermodynamical, and micro- and macrophysical properties of aerosols, clouds, and precipitation with high spatial and temporal resolution within a cube of approximately 10 × 10 × 10 km3. HOPE data will significantly contribute to our understanding of boundary layer dynamics and the formation of clouds and precipitation. The datasets have been made available through a dedicated data portal. First applications of HOPE data for model evaluation have shown a general agreement between observed and modelled boundary layer height, turbulence characteristics, and cloud coverage, but they also point to significant differences that deserve further investigations from both the observational and the modelling perspective.
