Wind information has been estimated with geostationary satellite data for many years (Velden et al., 2005) and more recently using polar-orbiting satellites (Key et al., 2003). However, from the point of view of the Antarctic, there is a latitudinal gap in coverage between these two wind sets as depicted in Figure 1. This has inspired an investigation using Antarctic composite imagery – a combination of geostationary and polar orbiting observations (Lazzara et al., 2003) – for the generation of atmospheric motion vectors (AMV),. One requirement for this investigation is to increase the temporal resolution of the infrared Antarctic composites from three-hourly to hourly, thereby providing wind
