Spectral information retrieval from integrated broadband photodiode Martian ultraviolet measurements

• We propose an algorithm to retrieve the global features of the spectral dependence of the ultraviolet (LTV) irradiance from integrated, broadband LTV measurements performed with a set of photodiodes with different LTV filters. This fit, when applied to ground-based measurements and compared with the incident Solar spectral irradiance on the top of the atmosphere, may be used to extract the spectral dependence of the LTV opacity and the most relevant parameters characterizing the scattering with atmospheric aerosol (Angstrom exponent, etc.) as well as the biological effective doses. In this way, using a set of photodiodes instead of a spectrophotometer, one may get spectral information within very low mass, package, and weight constraints, which is particularly useful for space missions. We consider its application for the rover-based exploration of the Martian ground, which is subject to daily and seasonal opacity variations
