thermosphere, region of increasing temperature in Earth’s atmosphere that is located above the mesosphere. The base of the thermosphere (the mesopause) is at an altitude of about 80 km (50 miles), whereas its top (the thermopause) is at about 450 km.
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.
The thermosphere is a layer of Earth's atmosphere that is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above Earth's surface.
11 Οκτ 2024 · The Short Answer: What is the thermosphere? The thermosphere is a layer of Earth’s atmosphere. The thermosphere is located above the mesosphere and below the exosphere. The heat that won't keep you warm. The thermosphere lies between the exosphere and the mesosphere.
13 Μαΐ 2019 · What are the spatial and temporal scales and the variability of atmospheric waves in the thermosphere, what is their latitudinal structure, and what is their role in driving large-scale circulation in the mesosphere and lower thermosphere?
The thermosphere and ionosphere are at a transition zone from the Earth’s atmosphere to outer space, and have important functions in the Earth system and for human society.
Synopsis. The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.
