How hot in the deserts

eha

What are average high temperatures in the middle of the deserts during hot summer times? A sattelite has recorded a surface temperature of 71 Celcius (159 F) in Lut Desert in 2005, however no given date or season in 2005. How about temperatures above 1,5 m from the ground and in other hot deserts of the world?

The temperature of a surface in the sun depends on the emissivity (how black) of the surface and the angle to the sun - that's why temperatures are normally quoted 'in the shade'.
The air temperature near the surface is going to be close to the surface temperature.

I think satellites are measuring the temperature of surfaces of the other deserts regularly, but i can't get to those figures at the moment. Thanks for your interest.

Some deserts are not all that hot, but if you're curious about hot deserts, then...

Satellites measure the troposphere, not the surface.
