Abstract:
We present infrared spectrometer MIRS constructed for studying the spectral composition and spatial distribution of the nightglow and aurora in the near infrared region. The spectrometer allows a spectral image along the main arc of sky hemisphere in the spectral range 730-900 nm with a spectral resolution of about 0.7 nm and a rate of 4 frame/min. Its optical scheme has a classical composition with transmission grating. The instrument can work either offline or as a part of a computer network. The preliminary results obtained at Barentsburg (Spitsbergen archipelago) in the winter season of 2008/09 demonstrate that the MIRS spectrometer is an informative tool for studying processes in the upper atmosphere. When combined with an all-sky camera MIRS provides the broad view of the general auroral situation, that is necessary for research of geophysical events at high latitudes. The software used in data acquisition system offers an extensive range of operation modes. The device is operable under the most heavy field conditions in Arctic.
