Cross beam weather watch study

An optical cross beam correlation method has been proposed as a remote measuring system for atmospheric studies. Atmospheric measurements are limited due to the difficulty of placing measuring instruments at the desired location. Although meteorological towers and balloon flights are able to obtain wind data, they are greatly limited in their location. Thus, a real need exists for remote-sensing instrumentation in atmospheric measurements. Previous methods proposed to remotely sense atmospheric conditions include several types of microwave units, acoustic sounders, infrared sensors, optical sensors, and related laser techniques. The evaluation of a simple visible optical technique as a possible remote measuring system is discussed. A feasibility study of field tests of the instrumentation at meteorological sites is reported.
