The Earth From the Air

Product Information

Earth from the Air Millennium Square is set to become a 24-hour art gallery this autumn. The stunning Earth from the Air exhibition will be in Leeds from Thursday 15 September - Wednesday 16 November 2005.

Yann Arthus-Bertrand travelled to Kenya to study the Lions. It was then that he became interested in photography. a b Zahnle, K.; Schaefer, L.; Fegley, B. (2010). "Earth's Earliest Atmospheres".

The stratosphere is the second-lowest layer of Earth's atmosphere. It lies above the troposphere and is separated from it by the tropopause. This layer extends from the top of the troposphere at roughly 12km (7.5mi; 39,000ft) above Earth's surface to the stratopause at an altitude of about 50 to 55km (31 to 34mi; 164,000 to 180,000ft). Geometric altitude vs. temperature, pressure, density, and the speed of sound derived from the 1962 U.S. Standard Atmosphere. The upper limit varies depending on the definition. Various authorities consider it to end at about 10,000 kilometres (6,200mi) [23] or about 190,000 kilometres (120,000mi)—about halfway to the moon, where the influence of Earth's gravity is about the same as radiation pressure from sunlight. [22] The geocorona visible in the far ultraviolet (caused by neutral hydrogen) extends to at least 100,000 kilometres (62,000mi). [22] The ionosphere is a region of the atmosphere that is ionized by solar radiation. It is responsible for auroras. During daytime hours, it stretches from 50 to 1,000km (31 to 621mi; 160,000 to 3,280,000ft) and includes the mesosphere, thermosphere, and parts of the exosphere. However, ionization in the mesosphere largely ceases during the night, so auroras are normally seen only in the thermosphere and lower exosphere. The ionosphere forms the inner edge of the magnetosphere. It has practical importance because it influences, for example, radio propagation on Earth.

The combined absorption spectra of the gases in the atmosphere leave "windows" of low opacity, allowing the transmission of only certain bands of light. The optical window runs from around 300nm ( ultraviolet-C) up into the range humans can see, the visible spectrum (commonly called light), at roughly 400–700nm and continues to the infrared to around 1100nm. There are also infrared and radio windows that transmit some infrared and radio waves at longer wavelengths. For example, the radio window runs from about one centimetre to about eleven-metre waves.

About 78% of the atmosphere is nitrogen gas, N2, which is unreactive and just sort of hangs around.Exosphere - overview". UCAR. 2011. Archived from the original on 17 May 2017 . Retrieved April 19, 2015.
