An important reason for the large daily temperature range over deserts is:

The light-colored sand radiates heat very rapidly at night
The ozone content of desert air is very low
Free convection cells are unable to form above the hot desert ground
There is little water vapor in the air to absorb and re-radiate infrared radiation
Dry air is a very poor heat conductor
