The proposed project seeks to further develop and field a Micro-pulse DIAL (MPD) Lidar system. This system will be used by researchers to advance our knowledge in the areas of measuring water vapor concentration and distribution, convective initiation, and land-atmosphere exchange. This new system will potentially advance our ability to better predict weather, particularly in the area of storm development. The proposed major research instrumentation (MRI) project seeks to develop and make available to the science community a system of five diode-laser-based, micro-pulse, differential absorption lidar (DIAL) instruments for measuring the spatial and temporal distribution of water vapor in the lower atmosphere. The Micro-Pulse DIAL (MPD) instruments will build on the proven design developed by the PI and Co-PI, including development of enclosures to make the system more field deployable and network attachable for remote access. Once the testing phase is complete, the MPD research instrumentation will be made available to the science community through the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory (EOL) Facilities and Instrument Program.

拟议项目旨在进一步开发和部署微脉冲DIAL（MPD）激光雷达系统。 研究人员将使用该系统来提高我们在测量水汽浓度和分布、对流启动和陆-气交换等领域的知识。 这个新系统将有可能提高我们更好地预测天气的能力，特别是在风暴发展领域。 拟议的主要研究仪器项目旨在开发一个由五台基于二极管激光器的微脉冲差分吸收激光雷达仪器组成的系统，并向科学界提供该系统，用于测量低层大气中水汽的空间和时间分布。 微脉冲拨号（MPD）仪器将建立在PI和Co-PI开发的成熟设计基础上，包括外壳的开发，使系统更具现场部署性和网络连接性，以进行远程访问。 一旦测试阶段完成，MPD研究仪器将通过国家大气研究中心（NCAR）地球观测实验室（EOL）设施和仪器计划提供给科学界。
