Millimeter Wave Doppler Radar Observation of Cloud and Boundary Layer Structure

摘要

The project was concerned initially with the development of a Doppler radar operating a 94 ghz (3 mm wavelength) primarily for the study of dynamical processes in clouds in the early stages of their development. The observation of other weak targets such as particulates suspended in the earth's atmosphere was also included in the research as well as the study of snow cover done in cooperation with the University of Massachusetts. The radar was tested and extensively used for the obervation of cloud and precipitation, including observation of: cirrus density and motion, melting layer in a stratified cloud, particle vertical velocity in storms, and small cumulus kinematics and development.
