Acquisition of 95GHz Doppler Polarimeter Radar for FARS.

私人投资机构提议在大气遥感设施(FARS)中增加一台最先进的95 GHz(3.2毫米波长)雷达，该设施目前在犹他大学的永久结构中包括三个偏振激光雷达和各种被动传感器。这台可扫描的多普勒偏振雷达将包括以下云数据量：雷达在V和H面上的反射率因子，从而得到线性退偏率和差反射率，以及径向云粒子速度的测量和方差。系统敏感度应该可以进行从许多晴朗天气积云到高卷云的云研究。该雷达将被纳入正在进行的卷云火力研究项目，以增强数据集，并利用多个遥感传感器的方法提供对卷云特性的新见解，特别是在多普勒测量能力方面。过冷高积云层的测量将受到特别关注，并将作为混合相微物理、辐射和动力学模式的输入，以帮助回答关于这些层云的增长和成核的基本问题。

The PIs propose to add a state-of-the-art 95 GHz (3.2 mm wavelength) radar to the Facility for Atmospheric Remote Sensing (FARS), which currently includes three polarization lidars and a variety of passive sensors at their permanent structure at the University of Utah. This scannable Doppler polarimetric radar will yied the following cloud data quantities: radar reflectivitryu factors in the V and H planes, and hence linear depolarization ratios and differential reflectivities, and the measn and variance of radial cloud particle velocityu. System sensitivity should permit cloud studies ranging from many fair weather cumulus to high cirrus clouds. This radar will be integrated into the ongoing Project FIRE studies of cirrus clouds to enhance the datasets and and provide new insights into cirrus properties using the multiple remote sensor approach, and particularly with regard to the Doppler measurement capabilities. Measurements of supercooled altocumulus cloud layers will receive special attention, and will serve as inputs for mixed-phase microphysical, radiative and dynamical models to help answer basic questions about the growth and nucleation of these layer clouds.
