We use opacity values obtained at the surface from direct imaging of the Sun and our radiative transfer model COMIMART to analyze the seasonal and interannual variability of the daily irradiation at the MER and MSL landing sites. In addition, we analyze the behavior of the direct and diffuse components of the solar radiation at these landing sites.engjournal articlehttp://dx.doi.org/10.5209/rev_FITE.2016.v28.53900http://revistas.ucm.es/index.php/FITE/open access52Optical depthMartian atmosphereBoundary-layerMars aerosolSurfaceUltravioletOpacityBudgetIceAstrofísicaAstronomía (Física)
