Abstract

Analysis of near infrared hyperspectral images for the detection, mapping and characterization of surface materials on Mars requires the modeling and the correction of the atmospheric (gas and aerosols) spectral effects on the spectra. Thus we propose efficient radiative transfer algorithms and methods tailor-made for operational use in order to retrieve Mars surface reflectance. Our system addresses two important constrains: (i) the large number of spectra to be treated, of the order of 10⁵ for one single image (ii) the characteristics and availability of data covering martian regions of interest.
