And I guess that's why they call it "The red planet"...

Great spectrum Tony.  Is the relative flux effectively the same as emission (or emmitance) [that is, as opposed to absorption]. Are the sharp peaks that decrease in relative flux - absorption bands, i.e. the overall spectrum is emission and the large hump is showing strong emission in the red wavelengths toward the right hand side, and the (negative) peaks are absorption bands? If so, what are the absorption bands due to?  CO2, H2O? (in our atmosphere or Mars's).
