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.

小行星9321330 这项研究的目的是云粒子的远程测量。 威斯康星州大学的高光谱分辨率激光雷达（HSRL）将用于测量消光分布和激光雷达信号强度对接收器角度视场的依赖性。 随着视场的增加，多次散射光子提供了激光雷达回波的更大部分。 多重散射随视场的变化强烈地依赖于颗粒尺寸。 将开发算法来从这种依赖性推断颗粒大小。 将通过与空中原位测量结果进行比较来测试结果。
