Q: Would the maximum temperature of the ground (near the surface) on mars be lower or higher than the maximum temperature of the atmosphere?

I would guess that it would be lower. Assuming high temperature fluctuations, the amount of time it takes for the ground to "warm" up is too long. Does anyone for for sure?

I would have said no (ground is warmer) because the atmosphere absorbs at lot less of the suns radiation than the ground does. I only skimmed through the paper but it looks to me like the temperature graphs are air temperatures at different hights above the ground, not direct readings of ground temperatures. I believe viking did measure ground temperature directly and found it ten to fifteen kelvin warmer than the air, but I can't find the results. Could someone with more knowledge confirm this or set me straight?
