Three case studies were made from Tiros I and III photographs, radar data, and synoptic weather observations in order to develop and explore techniques for future evaluations of satellite cloud photographs. The Fujita rectification technique for Tiros photographs was used but it is very time consuming and does not remove the camera nadir angle and earth curvature distortions. The development and testing of a system is described whereby Tiros photographs are projected onto a section of a sphere representing the earths surface and rephotographed in order to rectify them geographically and remove earth curvature and camera nadir angle distortions. Although the process presently relies on knowledge of the positions of two points or one point, north orientation, and a scale factor and does not correct for satellite lens distortions beyond the establishing of the points used, it is entirely objective and should lend itself to an automated technique whereby small sections could be rectified well within tolerances needed for either operational or most research purposes.
