Raymond G. Roble received the Ph.D. from the University of Michigan and currently is a senior scientist at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. His research concentrates on the chemistry, physics, and dynamics of the upper atmosphere and on global atmospheric electricity. He has constructed a hierarchy of general circulation models of the coupled thermosphere/ionosphere/mesosphere system and his most recent model is called a Thermosphere/Ionosphere/Mesosphere/ Electrodynamics general circulation model (TIME-GCM) that extends between 30 to 500 km altitude range. These various general circulation models have been used to analyze data from the NSF CEDAR and GEM programs as well as the NASA programs, Atmosphere Explorer, Dynamics Explorer, Solar Mesosphere Explorer, Upper Atmosphere Research Satellite, the International Solar-Terrestrial Program/Global Geospace Science Programs, and the Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics satellite. He has served on numerous national and international committees and has authored and co-authored over 400 publications. He is a fellow of the American Geophysical Union and has received the Arctowski medal from the National Academy of Sciences. He is also highly cited in space sciences by the ISI (http://isihighlycited.com) and has received the World Meteorological Organization Norbert-Gerbier Mumm Award for co-authoring the paper "Review of Mesospheric Temperature Trends" published in Reviews of Geophysics in 2003 (http://www.wmo.ch/news/news.html).
