image: Imagery from the GOES satellite on Jan. 29, 2007. (Top) Circular and linear aircraft induced holes at 1632 UTC, and (Bottom) example of paths of multiple holes, with circles indicating the midpoint position of each hole or canal at 15-min intervals from first through last detection. An identifying hole number is given at the beginning time of the first detection of each hole. For more information, please see Figure 2 in the manuscript. This image relates to an article that appeared in the July 1, 2011, issue of Science, published by AAAS. The study, by A.J. Heymsfield of the National Center for Atmospheric Research (NCAR) in Boulder, Colo., and colleagues was titled, "Formation and Spread of Aircraft-Induced Holes in Clouds." view more
