""Wow!" "Amazing!" "Beautiful!" It's common to hear these exclamations from those lucky enough to view Nocticulent clouds (night shining clouds) on a summer night near the Arctic Circle.Their unusual occurrence and possible link to climate change has pushed them into the media spotlight over the last decade. In April 2007, NASA launched the AIM (Aeronomy of Ice in the Mesosphere) satellite specifically designed to understand these clouds better. Dr. Aimee Merkel discusses recent findings about PMCs and highlights work done at the University of Colorado on the AIM mission.
