Gerber/Abstract The objectives of this research are two-fold; (1) to analyze existing observations of cloud liquid water using a new optical device (PVM-100A) capable of high frequency sampling (2KHz), including the direct measurement of effective radius (volume divided by surface area). The high frequency measurements of liquid water (in Cumulus and stratorcumulus clouds) should illuminate the physics of entrainment; the effective radius seems to be a useful variable for radiative transfer and remote sensing applications; (2) to participate in a field experiment (SHEBA) devoted to the cloud physics of (summer) Arctic stratus, a cooperative program

Gerber/摘要 本研究的目的有两个方面：（1）使用能够高频采样（2KHz）的新光学设备（PVM-100 A）分析现有的云液态水观测结果，包括直接测量 有效半径（体积除以表面积）。 液态水（积云和层积云）的高频测量应阐明卷吸的物理学;有效半径似乎是辐射传输和遥感应用的一个有用变量;（2）参加一个专门研究（夏季）北极层云云物理学的现场实验（SHEBA），这是一个合作计划
