Abstract : The detailed development of two climatological data bases are presented. The first is a photographic sky cover data base from Columbia, Missouri consisting of the Regis College Research Center's interpretations of over 2800 photographs of the whole sky. It also contains point information taken from the photographs and concurrent NWS sky cover observational information. An analysis of the content of the data base, the derivation of sky cover frequency density relations, a comparison of other data from ETAC-USAF observations and an interval consistency study are included in this subsection. A second data base is taken from radar echo observations gathered from seventeen stations around the USA for a period of three years. The informational content of this data base is also summarized. The second half is a description of an interactive computer geopolitical mapping system of data displayed on the entire globe or regions of it. It is based on the Lambert azimuthal equal area projection. Development of the system, including coordinate systems, the equations of projection, and contour/map production, is discussed in detail. The emphasis is to explore means of bringing the power of modern computing facilities to bear on the problems of climatology.
