Abstract : Computer methods were used to process and analyse Tiros video camera and infrared radiometer data. Surface temperature and albedo estimates were made by applying certain derived calibration and correction functions to the Tiros data. The surface feature characteristics for high and low cloud, water, desert, land, ice and snow areas were explored by computer generated infrared displays, frequency scatter diagrams, and an infrared data correlation process. The radiation intensities emitted from a Rayleigh scattering atmosphere and received by a Tiros video camera were computed and results tabulated. An albedo estimating algorithm was derived from this scattering model and used to generate rectified, mapped and gridded albedo mosaics from calibrated Tiros video data. Automatic cloud cover analyses such as cloud amount, average albedo per unit area, and cloud banding indicators were performed. The method of determining cloud banding information was derived using a two-dimensional power spectrum analysis. (Author)
