Abstract : The Whole Sky Imager (WSI) is a ground-based system for assessment of cloud cover over the full upper hemisphere. Using a fish-eye lens and a slow scan CCD sensor, it acquires imagery through daylight, into moonlight and starlight conditions. At the start of this contract, the new Day/Night WSI was in brassboard configuration. This contract funding enabled MPL to complete assembly of the system, acquire system calibrations for measuring system characteristics, and develop algorithms for control of the system. The WSI was fielded and cloud decision algorithms were developed based on the acquired test data. (AN)
