An electronic system to study ATS photographs is described. Cloud pictures are scanned by a TV camera which inputs cloud data onto memory discs from which the data can be recalled and displayed on a cathode-ray tube. Display options include time-lapse, variable magnification and frame-to-frame differencing. Electronic cursors permit digital readout of displacements of identifiable cloud elements. Data handling techniques and the computer-data process for this system are described.
