The stratosphere (/ ... Near the equator, the lower edge of the stratosphere is as high as 20 km (66,000 ft; 12 mi), at mid-latitudes around 10 km ...
The atmospheric pressure at the top of the stratosphere is roughly 1/1000 the pressure at sea level. It contains the ozone layer, which is the part of Earth's atmosphere that contains relatively high concentrations of that gas. The stratosphere defines a layer in which temperatures rise with increasing altitude.
It contains a high concentration of ozone (O 3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer peaks at 8 to 15 parts per million of ozone, [ 1 ] while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million.
The BLAST high-altitude balloon just before launch on June 12, 2005. High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level.
The Ozone Crisis And Recovery. This hole in the ozone layer over Antarctica was discovered in the mid 80s and quickly took the world by storm. The ozone layer is located in the stratosphere, and ...
Stratosphere Tower: 350.2 m (1149 ft) 1996 Concrete Las Vegas, Nevada: Tallest observation tower in the United States. 2 Tower of the Americas: 228.6 m (750 ft) 1968 Concrete San Antonio, Texas: Built as the theme structure for San Antonio's World's Fair, HemisFair '68. It was the tallest observation tower in the United States from 1968 until ...
The stratosphere extends from the top of the troposphere to the bottom of the mesosphere, and contains the ozone layer, at an altitude between 15 km and 35 km. It is the atmospheric layer that absorbs most of the ultraviolet radiation that Earth receives from the Sun.
The project was orchestrated by Stations at High Altitude for Research on the Environment (SHARE), which also placed the Mount Everest webcam in 2011. [85] [86] The solar-powered weather station is on the South Col. [87] Mount Everest extends into the upper troposphere and penetrates the stratosphere. [88]
