Delivery and Development of a Day/Night Whole Sky Imager with Enhanced AngularAlignment for Full 24 Hour Cloud Distribution Assessment

摘要

The Whole Sky Imager is a ground-based digital imaging system for assessment ofcloud cover over the full upper hemisphere. Using a fisheye lens and a slow scan CCD sensor, it acquires imagery under daylight, moonlight and starlight conditions. This contract funding enabled Marine Physical Lab to provide a new Whole Sky Imager to the Air Force, with several enhancements. The primary enhancements funded under this contract included more accurate alignment with respect to the sky field, detailed documentation, and enhancement of the software to allow interactive modification of the data acquisition from remote sites.
