The Response of Optical Array Spectrometers to Ice and Snow: A Study of Probe Size to Crystal Mass Relationships

Abstract

This report is a summary of work performed by Particle Measuring Systems, Inc., to study the response of Optical Array Spectrometers to ice and snow crystals. The principle objective of this study was to perform laboratory, field and theoretical studies to establish more appropriate optical array probe particle size-to-mass relationships. The studies involved both 1-D and 2-D optical array spectrometers. The following report briefly describes the work performed and the results. The sections are not necessarily organized in the chronology that they were performed. While it was intended that the theoretical work might be performed prior to field studies it was necessary to modify theoretical models based upon field observations. In many cases, phases of this work proceeded essentially in parallel with considerable readjustment upon integrating all phases of work.
