So in the mid day sun, after some rotation of the ground based mirror,
it might then be possible to focus the reflected light from the

dish on the ground. The idea I had was that the light, reflecting down
from space through the earth’s atmosphere could be used to heat a
narrow column of the atmosphere to extremely high temperatures.

The atmosphere, being transparent to radiation that you suggest,
would not heat.
