Spectra of the emitted light from an arc formed on an ice surface over a wide range (300-850 nm) were studied using a triggered spectrometer. Detailed analysis of the spectra allowed identifying different atomic lines and molecular bands from the background gases, as well as excited species from polluted ice. Time-resolved spectra were recorded at different stages of arc propagation over an ice surface to gather data on the occurring ionization processes.
