The resistance of the atmosphere decreases with altitude .The reason for this is that high altitude atmosphere is exposed to severe UV rays, which tear electrons apart from the air molecules. The result is high altitude atmosphere is a mixture of ions and electrons, what is called a Plasma.

The presence of ions is the reason why the high atmosphere is called the Ionosphere (It lies 75-1000 km). The presence of  free ions and electrons, allows easier electrical conductivity, since they are available to carry a current
