Abstract—We demonstrate the feasibility of filament-induced breakdown spectroscopy (FIBS) for remote
sensing of solid samples in a polar environment. FIBS spectra from an aluminum target induced by 800-nm
laser pulses propagating in air were probed. The air visibility in an open winter field was as low as 3.2 km fluc-
tuating with precipitation, pressure and relative humidity. Under such polar condition, clean spectral Al I lines
from an aluminum target located at a distance of 60 m were obtained. This shows the technique FIBS could be
potentially useful for sensing remote targets in a variety of polar environments.
