Important features in meteor spectra are usually interpreted by synthetic convolution of lines extracted from databases. For such an assignment, in our study, we employed experimental technique of meteorite specimen laser ablation spectroscopy. The spectra are recorded by high resolution laboratory Echelle spectrograph and simultaneously using novel high resolution Meteor Spectral Camera for meteor observation. The data are subsequently evaluated via calibration-free method alongside with analysis of real meteor emission spectra. Additionally, spectral features related to airglow plasma are compared with the spectra of the Laser Induced Breakdown in the air. In this manner, we show that instead of theoretical spectra simulation, laboratory experiments can be applied in evaluation of the observational data.
