The top of the thermosphere is the bottom of the exosphere, called the exobase.

As the temperature of the thermosphere cools, it contracts to lower altitudes.

The other layers of the atmosphere are the mesosphere and the thermosphere.

The thermosphere always cools and contracts when solar activity is low.

Extra CO2 in the thermosphere could have magnified the cooling action of solar minimum.

The atmospheric layer between the mesosphere and the exosphere
The Earth atmosphere between 120 and 250 to 400 km (depending on the solar and geomagnetic activity levels), where temperature has an exponential increase up to a limiting value Texo at the thermopause. The temperature Texo is called the exospheric temperature.
A thermal classification, it is the layer of the atmosphere located between the mesosphere and outer space. It is a region of steadily increasing temperature with altitude, and includes all of the exosphere and most, if not all, of the ionosphere.
The layer of the atmosphere lying between 100 - 400 km altitude. More information here.
The highest layer in the atmosphere, where atoms absorb solar energy resulting in warming of the air to as high as 3,600 F.
Area of the earths atmosphere located more than 90 km above the surface
