Abstract : During the period from 1959 to 1963, the National Research Council, in co-operation with a number of other agencies, participated in an experimental study of the physics of precipitation. Although an immediate objective of this study was the determination of the efficacy of silver-iodide seeding of clouds as a means to augment rainfall over the forest regions of western Quebec, the long-range objective was the advancement of the knowledge of fundamental precipitation mechanisms by the measurement and correlation of rainfall and of the basic properties of cloud and atmospheric parameters. Temporal and geographic control of the dissemination of the silver-iodide seeding material and in-flight measurements of cloud and atmospheric parameters were obtained by the use of a specially instrumented aircraft provided by the Flight Research Section of the National Research Council. This report describes the airborne instrumentation and assesses the accuracy of the measurements. (Author)
