Rotating Multicylinder Method for the Measurement of Cloud Liquid-Water Content and Droplet Size

Abstract

Since its development at the Mt. Washington Observatory in the 1940s the rotating multicylinder (RMC) method has been the simplest, most reliable, and usually the most accurate means of measuring the liquid-water content and droplet size in clouds and fog. The development history of the method is reviewed in this report. Fabrication of the instrument, exposure and data- reduction techniques, and the underlying theory of the method are described in detail. Accuracy of the RMC method is discussed and comparison tests with other instruments are briefly reviewed.
