The ANtarctic Gravity Wave Instrument Network (ANGWIN) is an NSF sponsored international program designed to develop and utilize a network of gravity wave observatories using existing and new instrumentation operated at several established research stations around the continent. The primary goal is to better understand and quantify large-scale gravity wave climatology and their effects on the upper atmosphere over Antarctica. ANGWIN currently comprises research measurements from five nations (U.S., U.K., Australia, Japan, and Brazil) at seven international stations. Utah State University’s Atmospheric Imaging Lab operates all-sky infrared and CCD imagers and an Advanced Mesospheric Temperature Mapper (AMTM) imager at several research stations (Davis, Halley, Rothera, McMurdo, and South Pole). We present new measurements of short-period mesospheric gravity waves imaged from McMurdo Station (77°S, 166°E) on Ross Island. This camera has operated alongside the University of Colorado Fe Lidar during the 2012 winter season (March-September 2012). Image data were recorded every ~10 seconds enabling detailed measurements of individual gravity wave events in the infrared OH emission layer (~87 km). Here we present example wave data and novel measurements of the wave characteristics observed during this winter season.
