ID-92 : Spectral observations of aurora and airglow at Longyearbyen
Type
FIELDWORK
Research/Observation Title
Spectral observations of aurora and airglow at Longyearbyen
Science Summary (common)
[purpose] Studies on how the auroral and airglow spectra change both spatially and temporally with respect to changes in the upper atmospheric environment.
[outline] The auroral spectrograph consists of a large fish-eye lens (180-degree FOV，f=6 mm，F1.4)，a slit which passes the light from the sky along meridian direction， a collimating optics，a grism with 600 gr/mm，an imaging optics，and a digital camera with a bare，back-illuminated CCD chip of 512 x 512 pixels. The spectrograph covers a wavelength of 420-740 nm with spectral bandwidth of 0.6 nm，and with spatial resolution of 0.18 x 0.18 degrees. The sensitivity is 0.06 counts/pixel/Rayleigh/sec which enables sampling rate of a few seconds per image. This also contributes to the collaborative study with the EISCAT Svalbard Radar (ESR) and other ground-based observations.
