The ATISE experiment is a spectrometer destinated to the observation of aurorae. This is an ultra-sensitive spectrometer, allowing to obtain continuous observation of the auroral spectra. These spectra then allow to reconstitute the energetic inputs into the upper atmosphere, in particular the low energy electrons between 20 eV and 30 keV.
The Ny-Ålesund region, located in the polar cusp but in view of the oval, is ideally situated to obtain information on the precipitations both in the auroral zone and in the cusp, region in which precipitates a flux of lower energy particles, named the “polar rain”. It is therefore ideal place for the study of these phenomena.
