GI postdoc presents at NSF CEDAR-GEM meeting

July 13, 2011


In June, Callum Anderson of the Geophysical Institute’s Space Physics group presented at the 2011 Coupling, Energetics and Dynamics of Atmospheric Regions and Geospace Environment Modeling summer workshop. 


As part of a Science Highlight session, Anderson discussed “Exploring Flow Structures of Thermospheric Winds using a Bistatic Array of All-sky Imaging Fabry-Perot Spectrometers.” The presentation resulted from joint research conducted by the GI, the U.S. Air Force Academy and independent research group SRI International. The collaborative effort involved use of spectrometers at the GI’s Poker Flat Research Range and the High Frequency Active Auroral Research Program facility near Gakona, Alaska. 


By combining the data collected at both PFRR and HAARP the researchers created a bistatic array and captured “more accurate, high resolution maps of the horizontal wind” in the auroral ionosphere, Anderson said. Moving forward with this research, the collaborators hope to further improve upon scientific understanding of neutral flow structure with tristatic wind imaging – an effort that will be realized as more all-sky Fabry-Perot spectrometers are installed. 


This year’s CEDAR-GEM meeting was held at the Santa Fe Convention Center and focused on the theme “Exploring Connections in the Geospace System.” Anderson was nominated to present by GI Assistant Professor Mark Conde.
