The thermosphere (or the upper atmosphere) is the height region above 85 km, while the region between the tropospause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near 45 km altitude and causes the ozone layer.ithin this layer, ultraviolet radiation causes photoionization /photodissociation of molecules present. Called from the Greek Î¸ÎµÏÎ¼ÏÏ (pronounced thermos) meaning heat, the thermosphere begins about 85 kilometres (53 mi) above the Earth.
