Calibration-free quantitative elemental analysis of meteor plasma using reference laser-induced breakdown spectroscopy of meteorite samples
Original language description
Aims. We aim to analyse real-time Perseid and Leonid meteor spectra using a novel calibration-free (CF) method, which is usuallynapplied in the laboratory for laser-induced breakdown spectroscopic (LIBS) chemical analysis.nMethods. Reference laser ablation spectra of specimens of chondritic meteorites were measured in situ simultaneously with a highresolutionnlaboratory Echelle spectrograph and a spectral camera for meteor observation. Laboratory data were subsequently evaluatednvia the CF method and compared with real meteor emission spectra. Additionally, spectral features related to airglow plasma werencompared with the spectra of laser-induced breakdown and electric discharge in the air.nResults. We show that this method can be applied in the evaluation of meteor spectral data observed in real time. Specifically, CFnanalysis can be used to determine the chemical composition of meteor plasma, which, in the case of the Perseid and Leonid meteorsnanalysed in this study, corresponds to that of the C-group of chondrites.
