   The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.

   NASA’s heliophysics researches the ionosphere-thermosphere-mesosphere region where our neutral atmosphere transitions into the ionized plasma of space. In this thin shell that surrounds our home planet, the atmosphere is in constant motion, shaped by the influence of both solar activity and changes in the lower atmosphere and in near-Earth space.

   Thermosphere • Near the bottom of the thermosphere (~100 km), the neutrals are well mixed and have the same rate of decreasing. • Above this height, the neutral densities decrease according to their own scale height. • During solar maximum, the solar radiation is higher than that during solar minimum. So the
