Abstract: Reflectance spectra (0.65–2.50 μm) are presented for 11 Martian areas. The spectral resolution is ∼1½% and the spatial resolution is 1000–2000 km. These are the first high‐quality spectrophotometric data at these wavelengths for regions on the surface. Spectral features previously observed are confirmed and better defined, and a number of important spectral properties are characterized for the first time. The spectra show water ice absorptions in the 1.5‐ and 2.0‐μm regions, which if due to surface frost, would imply the presence...
