Simultaneous Observation of Cool Cloud Liquid by Ground-Based Microwave Radiometry and Icing of Aircraft

Abstract

An example of measurement of liquid water in a cool cloud deck by microwave radiometry and simultaneous observation of icing of aircraft is given. Implications in use of microwave radiometers for warning of icing conditions, and in weather-modification application, are discussed. The liquid in the cloud is shown to be supercooled by supporting evidence from the National Weather Service radiosondes at Denver, Colorado.
