Sassen/Abstract The object of this research is to utilize the unique, climatologically representative Facility for Atmospheric Remote Sensing (FARS) cirrus cloud dataset, collected over the past 10-y in support of Project FIRE, combined with a focused program of additional state-of-the-art remote sensor cloud case studies, to prepare a series of publications on the synoptic, physical, microphysical, and radiative properties of high clouds at our midlatitude location. As of this time, over 2,100-h of FARS ruby (0.693) lidar data have been collected, while more recently- acquired research capabilities including scanning dual-wavelength (PDL, 1.06 and 0.532) polarization lidar, 95 GHz polarimetric Doppler radar, cologned midinfrared radiometer, all-sky imagery, and a suite of hemispherical and solar tracking radiometers. The advanced new multiple remote sensor datasets will also aid in student and staff training, and in the evaluation of the prospects of 95GHz radar for cloud research. Among the topics in our analysis program are; statistical studies of the monthly-averaged heights, temperatures, and visible/infrared radiative properties of cirrus; their synoptic causes, structures from the cloud-to- mesoscales, inferred contents from lidar linear depolarizations ratios, and an illustrated cirrus cloud atlas; and, finally, the local (Great Basin) peculiarlarities of contrails, anvils, cirrus optical phenomenon, deep cirrus/altostratus, and supercooled liquid water in high and middle level clouds.

萨森/摘要 本研究的目的是利用独特的、气候学上具有代表性的大气遥感设施（法尔斯）卷云数据集，该数据集是在过去10年中为支持FIRE项目而收集的，结合一个重点项目，即额外的最先进的遥感器云案例研究，以编写一系列关于天气、物理、微物理、以及中纬度地区高云的辐射特性。 到目前为止，已经收集了超过2,100小时的法尔斯红宝石（0.693）激光雷达数据，而最近获得的研究能力，包括扫描双波长（PDL，1.06和0.532）偏振激光雷达，95 GHz偏振多普勒雷达，科隆中红外辐射计，全天空图像，以及一套半球和太阳跟踪辐射计。 先进的新型多遥感器数据集还将有助于学生和工作人员的培训，并有助于评估95 GHz雷达用于云研究的前景。 在我们的分析计划的主题是：卷云的月平均高度，温度和可见光/红外辐射特性的统计研究，它们的天气原因，从云到中尺度的结构，从激光雷达线性去偏振比推断的内容，并说明卷云图集;最后，还讨论了高空和中层云中的凝结尾迹、砧状云、卷云光学现象、深卷云/高层云和过冷液态水的局部（大盆地）特征。
