The Measurement of Particle Sizes in Clouds with the University of Wisconsin High Spectral Resolution Lidar

9321330埃罗兰塔这项研究的目标是对云层粒子进行远程测量。威斯康星大学的高光谱分辨率激光雷达(HSRL)将被用来测量消光轮廓和激光雷达信号强度与接收器角度视场的关系。随着视场的增大，倍增散射光子提供了更大比例的激光雷达回波。多次散射随视场的变化与颗粒大小密切相关。将开发算法来根据这种依赖关系推断颗粒大小。结果将通过与航空现场测量进行比较来检验。

9321330 Eloranta The objective of this research is the remote measurement of cloud particles. The University of Wisconsin High Spectral Resolution Lidar (HSRL) will be used to measure the extinction profile and the dependence of lidar signal strength on the angular field of view of the receiver. As the field of view is increased, multiply scattered photons provide a larger fraction of the lidar return. The variation of multiple scattering with field of view is strongly dependent on particle size. Algorithms will be developed to infer particle size from this dependence. Results will be tested by comparison with airborne insitu measurements.
