Abstract:

In 1959 Ronne developed a system of measuring film taken by a time-lapsed motion picture camera mounted in an aircraft so that cloud heights and distances could be computed. The measurement system has been redesigned and a Fortran program has been written for the computation of distances and heights. Utilizing the phenomenon that the bases of cumulus clouds in a given air mass have nearly the same height, a method of determining the level line when the horizon is obscured by haze or clouds has been devised and incorporated into the program.
