The temperature of the ionosphere ranges from about 200K, or -73 ÂºC (-99.4 ÂºF) to 500K, or 227 ÂºC (440.6 ÂºF).So basically at the bottom it is 200K. At the top it is 500K.K is in Kelvin.he temperature of the ionosphere ranges from about 200K, or -73 ÂºC (-99.4 ÂºF) to 500K, or 227 ÂºC (440.6 ÂºF). So basically at the bottom it is 200K. At the top it is 500K. K is in Kelvin.
Temperatures in the upper thermosphere can range from about 500Â° C (932Â° F) to 2,000Â° C (3,632Â° F) or higher. The boundary between the thermosphere and the exosphere above it is called the thermopause.At the bottom of the thermosphere is the mesopause, the boundary between the thermosphere and the mesosphere below.olar activity strongly influences temperature in the thermosphere. The thermosphere is typically about 200Â° C (360Â° F) hotter in the daytime than at night, and roughly 500Â° C (900Â° F) hotter when the Sun is very active than at other times.
