Thermal inertia and albedo are derived from ground temperature measurements along the Curiosity rover's traverse. Diffuse water ice clouds or hazes can significantly influence ground temperatures in the southern fall and winter. The shape of the diurnal ground temperature curve is used to isolate the bedrock thermal inertia from other materials within the sensor footprint. Thermal inertias of sedimentary rock may be significantly higher than apparent in data sets with sparse local time coverage.
