Example comparing thermal inertia map with elevation, albedo, and dust.

Which best matches thermal inertial more: elevation data, dust, albedo, or dust coverage data?

Do you think the Mars dusty cover affects collecting data, such as what is beneath the surface?

White areas represent high emission of light from the surface.

Note on histogram color chart:

Dark blue/magenta end of the chart represents minimal dust coverage, while red represents maximum dust coverage.

Hint: From above reference; "It is widely accepted that the lowest thermal inertia regions on the planet must be mantled with dust at least a few centimeters thick." The curve on the histogram color key chart indicates how the silicate dust reflects more strongly at certain wavelengths.
