STUDY ON DROP SIZE DISTRIBUTION MEASUREMENT IN CLOUD BY USING VIDEO SONDE AND SCALE-RM

Abstract

 This study aims to develop a measurement strategy for drop size distribution (DSD) in the cloud. It is challenging to estimate quantitative DSD using a video sonde because it has a small window to capture precipitation particles. The present study proposes a sampling number to ensure the quantitative DSD with numerical simulation using the bin type simulation model, SCALE-RM. Then, it compares the DSD measured by a video sonde observation and radar data through the cloud water content.
