Using cloud photographs taken by a U-2 aircraft equipped with a 180-deg panormaic camera, a technique of rectifica tion is described. Mosaics of 13 passes over the San Francisco Mountains were made with the rectified cloud photographs. Computations of cloud movement and change in the horizontal area of cloud were made by use of cloud and cloud shadow. It was found that the computed cloud motions are within the range of the wind speeds reported from nearby upper air reporting stations. Author
