9871398麦金托什了解云和降水的物理是必要的，以解决各种各样的气象问题，从雨的形成，通过云的辐射特性，这是重要的许多问题的气候和全球气候变化。 主要研究人员将开发一套先进的机载仪器，这将允许更好的数据收集比迄今为止可能的云系统的水预算。 这套仪器被命名为主动-被动毫米波遥感系统（AMRS）。 完整的系统将由一个云剖面雷达（发射频率为95 GHz）和两个（20.6和31.6 GHz）辐射计组成。 AMRS将安装在怀俄明州大学的KingAir国家飞机设施上，主要用于基础云物理研究。 连同现有的大量原位探测器，建议的ARMS将大大增加King Air的研究能力。95 GHz云层剖面雷达组件已经在先前的支持下开发。 这一独特的系统使许多关于云的结构和动力学的重要研究结果成为可能，这些研究结果现在已在文献中。 根据目前的拨款，主要研究人员将开发两个辐射计。 AMRS传感器的结合使用将大大提高了解云微物理和动力学的能力，并将有助于解决从降水产生到云对气候的影响等基本问题。 ***

9871398McIntosh Understanding of the physics of clouds and precipitation is necessary in order to address a variety of meteorological problems from rain formation through cloud radiative properties which are important to many issues on climate and global climate change. The Principal Investigators will develop an advanced suite of airborne instrumentation that will allow better data collection than heretofore possible on the water budget of cloud systems. This set of instruments has been named the Active-passive Millimeter wave Remote Sensing system (AMRS). The completed system will be comprised of a cloud profiling radar (transmit frequency of 95 GHz) and two (20.6 and 31.6 GHz) radiometers. AMRS will be mounted on the University of Wyoming's KingAir national aircraft facility and used principally for fundamental cloud physics research. Together with an existing extensive set of in situ probes, the proposed ARMS will substantially add to the King Air's research capabilities.The 95 GHz cloud profiling radar component has already been developed under prior support. This unique system has enabled numerous significant research findings about the structure and dynamics of clouds, which are now in the literature. Under the current grant, the Principal Investigators will develop the two radiometers. The combined use of the of AMRS sensors will represent a significant increase in capabilities for understanding cloud microphysics and dynamics and will help address fundamental problems that range from precipitation production to impact of clouds on climate. ***
