Abstract

Clouds and aerosols play an important role in the radiative processes affecting the Earth's climate and the thermodynamic properties of the atmosphere. Therefore, it is crucial to gain greater insight into the structure and composition of clouds and aerosols. One approach to achieving this consists of employing several different remote sensing systems operating at multiple wavelengths. At Penn State, an interdisciplinary group of researchers following this approach has developed a new research tool called WAVE-LARS (Water Aerosol Vapor Experiment-Lidar And Radar Sounder). This instrument includes a volume scanning 94 GHz radar, a volume scattering multi-wavelength lidar, and a vertically pointing Rayleigh/Raman lidar. The 94 GHz radar was based on a previous radar constructed at Penn State, augment ed with new volume scanning and polarization capabilities. This system provides vertical profiles of atmospheric water vapor and temperature. The theory, design, and initial results from the volume scanning lidar is discussed.<>

体扫描三波长偏振激光雷达的初步结果

云和气溶胶在影响地球气候和大气热力学性质的辐射过程中起着重要作用。因此，更深入地了解云和气溶胶的结构和组成是至关重要的。实现这一目标的一种方法是采用在多个波长上工作的几个不同的遥感系统。在宾夕法尼亚州立大学，一个跨学科的研究小组采用这种方法开发了一种新的研究工具，称为WAVE-LARS(水气溶胶蒸汽实验-激光雷达和雷达测深仪)。该仪器包括一个94 GHz体扫描雷达、一个体散射多波长激光雷达和一个垂直指向瑞利/拉曼激光雷达。94 GHz雷达是基于宾夕法尼亚州立大学之前建造的雷达，增加了新的体积扫描和极化能力。该系统提供大气水汽和温度的垂直剖面。讨论了体扫描激光雷达的原理、设计和初步结果。
