Wide Angle Infrared Cloud Imaging for Measuring Cloud Statistics
Previous research at Montana State University led to the development of the Infrared Cloud Imager (ICI) for measuring downwelling cloud and sky thermal emission for producing cloud coverage statistics using radiometrically calibrated images of the sky. This technique, that was developed primarily fo...

Previous research at Montana State University led to the development of the Infrared Cloud Imager (ICI) for measuring downwelling cloud and sky thermal emission for producing cloud coverage statistics using radiometrically calibrated images of the sky. This technique, that was developed primarily for detection of clouds for studies of arctic climate, provides benefits over commonly used systems by producing localized high resolution data in comparison to satellites images, and, in contrast to visible systems, provides continuous day and night operation. As a continuation of the first effort, in collaboration with the Optical Communications Group at the NASA’s Jet Propulsion Laboratory (JPL), here we present a new generation of the ICI that can be used to monitor the cloud coverage of a site that can house a ground telescope dedicated to Earth-space optical communication paths.
