Figure S1. Validation of the temperature vertical profiles from ACS MIR (T MIR) and ACS NIR (T NIR; Fedorova et al., 2022) retrieved over 1.5 considered Martian years. a: differences (T MIR-T NIR) as a function of altitude for all the simultaneous observations (green points) made during MY 34 and MY 35. Black curve is the average for points grouped in the altitude interval of 2 km, error bars are corresponding standard deviations. b: T MIR as a function ofT NIR. The gray dashed lines in these panels indicate the expected trend if T MIR =T NIR.
