2.2.0 spase://SMWG/Observatory/AIM AIM 2010-08-05T18:19:12Z AIM (Aeronomy of Ice in the Mesosphere) is a NASA Small Explorer spacecraft launched April 25, 2007, into a high-inclination, 600-km altitude orbit for study of noctilucent clouds (also called Polar Mesospheric Clouds) that occur at 80-90 km altitudes at high latitudes in summer time and are thought to be formed by ice crystals. AIM carried three instruments: * The Cloud Imaging and Particle Size (CIPS) experiment that provides an average 5km x 5km resolution in downward-looking images. * The Solar Occultation For Ice Experiment (SOFIE) for limb profiles of temperatures and absorptions for various molecules. * The Cosmic Dust Experiment (CDE). spase://SMWG/Person/James.M.Russell.III ProjectScientist AIM web page at Hampton University http://aim.hamptonu.edu/ Earth.NearSurface
