Top: continuum radiance map of the Martian disk recorded at 1241.50 cm^-1 on March 1, 2014 (Ls = 96°). Bottom left: brightness temperature TEXES map converted from the radiance map, assuming a surface emissivity of 1.0. The subsolar point is indicated with a white dot. The black circle corresponds to Region A where the TEXES spectra were modeled (see text). Bottom right: synthetic map of the surface temperature retrieved from the GCM under similar observing conditions.
