This all-sky imager observes infrared emissions during the night and operates on a high temporal cadence (an image every 10 seconds.)
This enables short period atmospheric gravity waves (thought to carry most of the energy and momentum in the gravity wave spectrum) to be observed. It is operated jointly by British Antarctic Survey and Bath University and is part of ANGWIN (Antarctic Gravity Wave Instrument Network).
Understanding gravity waves in Antarctica is important because they are the main driver of upper atmospheric circulation in this region.
