Temporal and spatial analysis has been applied to a sequence of cloud top pressure (CTP) images and cloud optical thickness (TAU) images stored in the International Satellite Cloud Climatology Project D1 database located at the NASA Goddard Institute for Space Studies. Each pixel in the D1 data set has a resolution of 2.5 degrees or 280 kilometers. These images were collected in consecutive three-hour intervals for the entire month of April 1989 and April of 1994. The primary objective of this project was to develop a sequence of storm tacks from the satellite images that could be compared tracks developed from sea level historical records. Composite images where created by projecting ahead in time and substituting the first available valid pixel for missing data and a variety of CTP and TAU cut-off values were used to identify regions of interest. Region correspondences were determined from one time frame to another yielding the coordinates of storm centers. These tracks were compared to storm tracks computed from sea level pressure data obtain from the NMC by first matching the result in time and then in spatial distance.
