This project will focus on in situ and remote sensing measurements of wintertime clouds over the Park Range of the Rocky Mountains in northern Colorado. These clouds are generally mixed-phase; the combination of ice, liquid and water vapor presents challenges both to measurements and modeling, and consequently, to understanding their impact on atmospheric radiation and on precipitation. The Colorado Airborne Multi-Phase Cloud Study (CAMPS) will use the Wyoming King Air research aircraft instrumented with both remote (cloud radar and cloud lidar) and in situ sensors (cloud and particle probes, total water hygrometer) to elucidate the vertical and horizontal structure of cold mixed-phase clouds.Intellectual Merit: The data gathered during CAMPS will include information about macro- and microphysical parameters of mixed-phase clouds obtained by both in situ and remote-sensing methods. These data will be analyzed to address a number of important questions about the structure, properties and impacts of mixed-phase clouds. Specific goals include:1. To assess the vertical and horizontal structure and spatial and temporal variation of cloud properties (particle size distribution, ice and liquid water content, particle habit) in liquid, mixed-phase and precipitating clouds at a mid-latitude continental site with complex terrain during winter.2. To assess the impact of topography and associated variations in vertical forcing on cloud generation and cloud properties.3. To develop a data set that provides the information necessary for improving the representation of mixed-phase clouds in cloud-resolving and climate models.4. To provide correlative data for validation of the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program mobile facility and the National Aeronautics and Space Administration A-Train satellite-borne remote sensors.5. To provide observational confirmation of the redistribution of snowfall associated with riming inhibition due to enhanced CCN. Broader Impacts: Ultimately, by enhancing the community's understanding of cloud-scale processes, the data from CAMPS will be the basis for improvements in the representation of clouds in global climate models. This will lead to more accurate calculations of current and future climate. In addition the CAMPS project will contribute to both formal and informal education at a number of levels. At least one graduate student from each of the participating universities will be involved with the field work and/or data analysis related to this project. The investigators will include undergraduates from their institutions in flight-planning and/or meteorology exercises related to CAMPS when possible. Formal educational opportunities for elementary school students will be coordinated by the Storm Peak Laboratory staff, including visits to the laboratory and aircraft and classroom exercises. Outreach activities will include signage at the Steamboat Springs Ski Resort, an interactive display at the gondola building and coordination with the 2011 Steamboat Weather Summit.

该项目将重点介绍在科罗拉多州洛矶山脉公园范围内的原位和遥感测量值。这些云通常是混合相的。冰，液体和水蒸气的结合提出了对测量和建模的挑战，因此，了解它们对大气辐射和降水的影响。科罗拉多州空降的多相云研究（CAMPS）将使用Wyoming King Air Research Intercraft，该飞机用远程（云雷达和云雷达）和原位传感器（云和粒子探针，总水湿表）来阐明complase clouds的垂直和水平结构。通过原位和遥感方法获得的云。这些数据将进行分析，以解决有关混合相云的结构，属性和影响的许多重要问题。具体目标包括：1。为了评估液体中云特性的垂直和水平结构以及云特性的空间和时间变化（液体尺寸分布，冰和液体水含量，颗粒习惯），混合相和在冬季具有复杂地形的中纬度大陆位置在冬季中的中间大陆位置。2。评估地形和垂直强迫对云产生和云特性的相关变化的影响3。为了开发一个数据集，该数据集提供了改善混合相云在云和气候模型中的表示所需的信息。4。提供相关数据，以验证能源部（DOE）大气辐射测量（ARM）计划移动设施和国家航空航天管理局A-Train卫星 - 卫星遥控传感器。5。为了对与CCN增强的抑制作用相关的降雪重新分布提供观察性确认。更广泛的影响：最终，通过增强社区对云规模流程的理解，营地的数据将成为改善全球气候模型中云代表的基础。这将导致对当前和未来气候的更准确计算。此外，营地项目将在许多层面上为正规和非正式教育做出贡献。来自每个参与大学的至少一名研究生将涉及与该项目相关的现场工作和/或数据分析。调查人员将在可能的情况下，包括与营地有关的飞行规划和/或气象练习的本科生。小学生的正式教育机会将由风暴峰实验室工作人员协调，包括参观实验室，飞机和课堂练习。外展活动将包括在Steamboat Springs滑雪胜地的标牌，在Gondola大楼的互动式展示以及与2011年Steamboat Weather Summit的协调。
