Mesosphere
The region of the 's atmosphere from roughly 50-80 km altitude.
mesosphere Region of Earth's atmosphere lying between the stratosphere and the ionosphere, 50-80 km above Earth's surface.

Mesosphere
The part of Earth's atmosphere immediately above the stratosphere, where the temperature drops from about 270 K to 180 K.

Mesosphere
The mesosphere is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the thermosphere. The mesosphere is located from about 50 km to 80-90 km altitude above the Earth's surface....

MESOSPHERE
The mesosphere is the atmospheric layer between the stratosphere and the ionosphere. The mesosphere is characterized by temperatures that quickly decrease as height increases.
-Mesosphere: The mesosphere is characterized by temperatures that quickly decrease as height increases. The mesosphere extends from between 31 and 50 miles (17 to 80 kilometers) above the earth's surface.
Solar Mesosphere Explorer (NASA Thesaurus) A satellite whose experiments provided a comprehensive study of atmospheric ozone and the processes which form and destroy it. The satellite was launched in October of 1981.
The Mesosphere and Ionosphere
Above the stratosphere is the mesosphere and above that is the ionosphere (or thermosphere), where many atoms are ionized (have gained or lost electrons so they have a net electrical charge).
Beyond that is the mesosphere, out to about 85 km, the mesopause, and temperatures drop rapidly down to about −110°C. Here be noctilucent clouds.
The anomalous propagation of sound refers to the downward refraction of an oblique sound wave from an explosion, the refraction occurring in the region of increasing temperature with height in the lower mesosphere.
Mesopause The temperature minimum at the boundary between the thermosphere and the mesosphere. It is the coldest place on Earth, with a temperature of âˆ'100 °C (âˆ'148.0 °F; 173.1 K).

Mesosphere: From the Greek word "μÎσος" meaning middle. The mesosphere extends from about 50 km (160,000 ft) to the range of 80 to 85 km (265,000 - 285,000 ft), temperature decreasing with height.

The atmospheric layers are - in order of distance from sea level - the troposphere (10 km), stratosphere (45 km), mesosphere (80 km), thermosphere (200 km), and exosphere (400 km).
Above the relatively warm stratopause is the even more tenuous mesosphere, in which temperatures again decline with altitude, reaching roughly -85 C at the mesopause.
The level above the stratosphere is the Mesosphere. Above the Mesosphere is the Thermosphere. Combined, the Thermosphere and the Mesosphere create the Ionosphere, which is 435 km (270 miles) thick.
"Our observations show that current understanding of the mesosphere-lower thermosphere region is quite poor," says co-author Charlie Seyler.
The transition region or mesosphere (for middle mantle), sometimes called the fertile layer, contains 11.1% of the mantle-crust mass and is the source of basaltic magmas.
The stratosphere is the atmospheric layer between the troposphere and the mesosphere. The stratosphere is characterized by a slight temperature increase with altitude and the absence of clouds.
Definition: stratosphere: The layer of the atmosphere above the troposphere and below the mesosphere where the temperature increases with height.
