Scientific objectives
Near InfraRed Aurora Camera (NIRAC):
The camera focuses on imaging dayside magnetosphere-ionosphere-atmosphere coupling processes in the high-latitude
polar region with high sensitivity in the Short Wavelength Infrared Region (SWIR) of the electromagnetic spectrum. It is used as a
twin instrument to the Near InfraRed Aurora and airglow Spectrograph-2 (NIRAS-2).
Two-dimensional structures of aurora (N2+) and even weak airglow (OH) and their temporal evolutions
can be visualized with a cadence of less than 30 seconds.
