Mesosphere

From Glossary of Meteorology



mesosphere

The region of the atmosphere lying above the stratosphere and extending from the stratopause at about 50 km height to the mesopause at 85–95 km.

The mesosphere is characterized by decreasing temperature with increasing height, reflecting the decreasing absorption of solar ultraviolet radiation by ozone. Many features of the mesosphere remain poorly understood since in situ measurements are difficult. The region is too high for balloon operations and too low for satellites to orbit. Rockets, while useful, usually travel too rapidly through the region to produce reliable measurements.
